Question

Sum of an angle and half of its complement angle is 75`. find the angle.

Answer 1

let one angle =x
complement angle =90-x
x+(90-x)/2=75
(2x+90-x)/2=75
x+90=2*75
x+90=150
x=150-90
x=60
one angle =x =60
second angle=30

Answer 2

Answer:

Step-by-step explanation:

let one angle =x

complement angle =90-x

x+(90-x)/2=75

(2x+90-x)/2=75

x+90=2*75

x+90=150

x=150-90

x=60

one angle =x =60

second angle=30
