Assertion and reason

16 x 1 = 16

50.

We know that Sides opposite to equal angles of a triangle are equal.
So, Reason is correct.
Since angles opposite to equal sides of an isosceles triangle are equal,
therefore a – 60° = 123° – 2a
⇒ 3a = 123° + 60° = 183°
⇒ a = = 61°
So, Assertion is also correct.
But reason (R) is not the correct explanation of assertion (A)
Correct option is (b) Both assertion (A) and reason (R) are true and reason (R) is not the correct explanation of assertion (A).

51.

We know that “If in two right triangles, hypotenuse and one side of a triangle are equal to the hypotenuse and one side of other triangle, then the two triangles are congruent.” – This is RHS Congruence Rule
So, Reason is correct
In ΔABD and ΔACD,
BD = CD (Given)
AB = AC (Given)
and AD = AD (Common side)
∴ By SSS congruence criteria, ΔABD ≅ ΔACD
So, Assertion is also correct.
Correct option is (b) Both assertion (A) and reason (R) are true and reason (R) is not the correct explanation of assertion (A).

52.

We know that “If two sides and the included angle of one triangle are equal to two sides and the included angle of the other triangle, then the two triangles are congruent” - This is SAS Congruence Rule.
So, Reason is correct.
In △AXC and △AYB, we have
AC = AB (Given)
AX = AY (Given)
and ∠BAC = ∠CAB   (Common)
∴ △AXC ≅ △AYB    (SAS criterion)
⇒ CX = BY   (CPCT)
So, Assertion is also correct
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

53.

We know that “In a triangle, angles opposite to two equal sides are equal.”
So, Reason is correct.
In ∆ABC, AB = BC
⇒ ∠A = ∠C (Angles opposite to equal sides)
Let ∠A = ∠C = x
Using angle sum property of a triangle,
∠A + ∠B + ∠C = 180°
⇒ x + 80°+ x = 180° ⇒ 2x = 180°− 80°
⇒ 2x = 100° ⇒ x = 50° ⇒ ∠A = 50°
So, Assertion is also correct
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

54.

We know that the sum of all the interior angles of a triangle is 1800. So, Reason (R) is true.
Let the angles of a triangle be 2x, 3x and 4x then we have 2x + 3x + 4x = 180^о
⇒ 9x = 180^о
⇒ x = 20^о.
Hence, Largest angle = 4 x 20^о = 80^о. So, Assertion (A) is also true.
Also, Reason (R) is a correct explanation of Assertion (A).
Correct option is (a) Both assertion (A) and reason (R) are true and reason
(R) is the correct explanation of assertion (A).

55.

We know that two angles are said to be supplementary if their sum of measure of angles is 180^о.
So, Reason is correct.
Now, 120^о + 60^о = 180^о ⇒ Sum of the pair of angles 120^о and 60^о is supplementary.
So, Assertion is also correct
Also, reason (R) is the correct explanation of assertion (A).
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

56.

For Assertion: We know that the exterior angle is equal to the sum of its interior opposite angles. So, x + x =110^о.
⇒ 2x = 110^о
⇒ x = 55^о
So, Assertion is correct
Also, we know that a triangle with one of its angle 90^о, is called a right triangle.
So, Reason is also correct.
But reason (R) is not the correct explanation of assertion (A).
Correct option is (b) Both assertion (A) and reason (R) are true and reason (R) is not the correct explanation of assertion (A).

57.

We know that two angles are said to be supplementary if their sum of measure of angles is 180^о.
So, Reason is correct.
Let the angle be x . Supplement of x = \(\frac{1}{4}\)x
So, x + \(\frac{1}{4}\)x = 180^о⇒ \(\frac{5}{4}\)x = 180^о ⇒ x = 144^о
So, Assertion is also correct
Also, reason (R) is the correct explanation of assertion (A).
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

58.

For Assertion: The given linear equation is x + y = 3
Since x = 0 and y = 0 is not satisfying x + y = 3, therefore it is not passing through the origin.
So, Assertion is not correct.
Since x = 0 and y = 0 is not satisfying y = 2x, therefore it is passing through the origin.
So, Reason is correct.
Correct option is (d) Assertion (A) is false but reason (R) is true.

59.

We know that a linear equation in two variables has infinitely many solutions. So, Reason is correct.
Since x = 2k - 1 and y = k is solution of the given linear equation, we have 3 x (2k – 1) – 5k – 7 = 0 ⇒ 6k – 3 – 5k – 7 = 0 ⇒ k – 10 = 0 ⇒ k = 10.
So, Assertion is also correct
But reason (R) is not the correct explanation of assertion (A).
Correct option is (b) Both assertion (A) and reason (R) are true and reason (R) is not the correct explanation of assertion (A).

60.

We know that the solution of the line will satisfy the equation of the line.
So, Reason is correct.
Since x = 2, y =1 is a solution of the given linear equation, we have
2 x 2 + 3 x 1 – k = 0 ⇒ 4 + 3 – k = 0 ⇒ k =7.
So, Assertion is also correct
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

61.

We know that a linear equation in two variables has infinitely many solutions.
So, Reason is correct.
Hence, Assertion is not correct
Correct option is (d) Assertion (A) is false but reason (R) is true.

62.

We know that Points of the type (–, +) lie in the second quadrant. So, Reason is correct.
Also, we know that Points of the type (+, –) lie in the fourth quadrant.
Hence, point whose abscissa is 2 and ordinate is -3 lies in fourth quadrant So, Assertion is also correct but Reason is the not the correct explanation of Assertion.
Correct option is (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

63.

We know that Every point on the x -axis has zero distance from x -axis and every point on the y -axis has zero distance from y -axis.
So, Reason is correct.
Now, point (-2, 0) lies on x-axis and (0, 4) on y-axis So, Assertion is not correct
Correct option is (d) Assertion (A) is false but reason (R) is true.

64.

We know that the if the point lies on y-axis, its x-coordinate is 0.
So, Reason is correct.
The x co-ordinate of the point (0, 4) is zero.
So, Point (0, 4) lies on y -axis.
So, Assertion is also correct
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

65.

We know that the perpendicular distance of a point from y-axis is called its x-coordinate or abscissa.
So, Reason is correct.
The x co-ordinate of the point (5, 2) is 5.
So, Assertion is also correct
Correct option is (a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
