Question

two angles are complementary. the sum of the measure of the first angle and half the second angle is 85 degrees. find the measures of the angles

Answer 1

Angle A=80 degrees.
Angle B= 10 degrees.
You can solve this by simultaneous equations.
A+B=90
A+B/2=85.

Answer 2

x and y
y=90-x =>x+y=90
x+y/2=85=>2x+y=170
x=80
y=10

Answer 3

Thank you.
