Question

(y-20) and (y+30) are the measures of complementary angle. Find the measures of each angle
please answer if you know it
otherwise don't answer
don't send silly answers
I will report it​

Answer 1

Answer:

2y+10=90°

2y=80°

y=40°

now, 1st angle is y-20=20°

and 2nd angleisy+30°= 70°

Answer 2

Answer:

Sum of two complementary angles is 90°

Therefore, (y-20)°+(y+30)°

=>y-20+y+30=90

=>2y+10=90

=>2y=80

=>y=40

Since, y=40°

Therefore, (y-20)°=20°

(y+30)°=70°

hence, the measures of two angles are 20° and 70°
