Find the complement of the following angles (1°= 60′ minutes, 1′ = 60′′ seconds)
70°
1.
\(\angle XOZ+\angle OZY=180^0\) (angle of a straight line)
(x° - 20°) + 60° = 180°
x°+40° = 180°
x° = 180°- 40°
= 140°
The value of x = 140°
2.
\(\angle AOB =90^0\)
\(\angle BOC +\angle COA=90^0\)
3x0+2x0 = 900
5x0= 900
\(x^0=\frac{90}{5}=18^0\)
The value of x = 18°
3.
Supplement of 121°48' = 180° - 121°48'
= 58°12′
4.
Supplement of Right angle (90°) = 180° - 90°
= 90°
5.
Supplement of 34° = 180° - 34°
= 146°
6.
Supplement of 140° = 1800- 140°
= 40°
7.
Complement of 62°32' = 90° - 62°32'
= 27°28′
8.
Complement of 45° = 900-45°
= 45°
9.
Complement of 27° =90° - 27°
= 63°
10.
Complement of 70° = 90° - 70°
=20°
