Question:
If an angle is 30° more than half of its complement, find the measure of the angle?
Solution:
Let the measured angle be 'x'
Hence its complement will be (90 - x)
It is given that,
Angle = 30 + complement/2
x = 30 + (90 - x) /2
$3 \frac{x}{2}=30+45$
3x = 150
x = 50
Therefore the angle is 50°
