Question

find the measure of the angle which is half of its complementary

Answer 1

Let angle be x Complementary angle vl be 90-x According to Q's: x= (90-x)/2 => 2x= 90-x =>3x= 90 => x= 30

Answer 2

Let the angle be x
ATQ,
x + (x/2) = 90
(2x + x) / 2 = 90
3x = 90 × 2
3x = 180
x = 180 ÷ 3
x = 60
×/2 = 30
Therefore, the angle is 30°.
