Question

If the m∠X = 34° and the m∠Z = 26°, what is the m∠Y?

Answer 1

<x+<y+<z=180°
34°+<y+26°=180°
60°+<y=180°
<y=180°-60°°
<y=120

Answer 2

Answer:120°

Step-by-step explanation:

as we know sum of all angle of triangle is 180°.

so

∠x+∠y+∠z=180°

34°+∠y+26°=180°

60°+∠y=180°

∠y=180°-60°°

∠y=120°

so the third angle is 120°.
