Answer 2

Step-by-step explanation:

Answer:

Given: (y-20) and (y+30)° are the measures of complementary angles.

Complementary angle states that sum of the two angle is 90 degree.

then,

(y-20) + (y +30) = 90

Combine like terms;

2y +10=90 or

2y = 90-10=80

Divide both sides by 2, we get

$\frac{2y}{2} = \frac{80}{2}$

Simplify:

y = 40°

The measure of each angle;

(y-20)°40-20 = 20° and

(y +30)° 40+30= 70°
