Respuesta :

∠s + ∠y are complementary
∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90
4y - 100 + y = 90
5y = 90 + 100
5y = 190
y = 38


Ans: y = 38°

The value of angle y is 40°.

Complementary angles are the angles that have their sum equal to 90°.

Therefore, based on the information given, the value of angle y will be calculated thus:

x + y = 90°.

4y - 110° + y = 90°

Collect like terms

4y + y = 90° + 110°

5y = 200°

y = 200/5

y = 40°

The value of angle y is 40°.
