Question

. Find the measure of an angle which is 30° more than its supplement
​

Answer 1

Answer

Given :-

Angle is 30° more than its supplementary

Let the angle be x

To find :-

Measure of angle (x)

Solution :-

• Angle - x
• Supplementary angle - 180 - x

According to the question :-

x = 180 - x + 30

x = 210 - x

2x = 210

x = 210/2

x = 105

Verification :-

Supplementary of 105 = 75

75 + 30 = 105.

Hence, our answer is correct
