Question

What is the measure of ∠y ?
Hint:∠z is a straight angle

Answer 1

∠y = 154°

Explanation:

- angle ∠z is a straight angle meaning it equals 180 180°

this is also known as...

supplementary angles (when two angles whose sum is 180°)

- one of the two angles are given:

angle 1: 26°

angle 2: ∠y °

26 + ∠y = 180 °

subtract 26 from both sides to get y alone

26 -26 + ∠y = 180 ° - 26

∠y = 154°

∠y is an obtuse which is confirmed by 154°

Answer 2

154

Explanation:

bc z is striaght line = 180

so 180 -26 = 154

remember

y + 26 = z
