Answer:
∠y = 154°
Step-by-step 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°
