Question

1.)Find the angle which is equal to its complement. (With full process) 2.)Find the angle which is equal to its supplement. (With full process)

Answer 1

1--->
Let the angle be x
both the angles are equal and hence both the angles are x
The sum of complementary angles is 90°

Thus x + x = 90°
2x = 90°
x = 90°/2
x = 45°

Hence the angle which is equal to its complement is 45°

2--->
Let the angle be x
both the angles are equal and hence both the angles are x
The sum of suplementary angles is 180°

Thus x + x = 180°
2x = 180°
x = 180°/2
x = 490°

Hence the angle which is equal to its suplement is 90°

Answer 2

1.) Let the angle be X
It's given that "X" is equal to it's supplement
Therefore, X = 90 - X
X + X = 90
2X = 90
X = 90 ÷ 2
X = 45° Ans.
2.) Let the angle be X
It's is given that "X" is equal to it's supplement
Therefore, X = 180 - X
X + X = 180
2X = 180
X = 180 ÷ 2
X = 90° Ans.
