Question

( y – 40 )° and ( y + 30 )° are the measure of complementary angles . Find the measure of each angle . answer fast urgent​

Answer 1

Answer:

1. y = 130°

2. y = 60°

Step-by-step explanation:

Complementary angles means that the sum of the angles is equal to 90°

Answer 2

y - 40 + y + 30 = 90
[two angles are complementary when their sum is 90]
y+y-40+30 = 90
2y - 10 = 90
2y = 90+10
2y = 100
y = 100/2
y = 50

Given angles :
(y - 40) = 50-40 = 10
(y + 30) = 50+30 = 80

CHECKING
We found the angles. As mentioned, two angles are complementary when their sum is 90.
10+80 = 90 degree
