Question

Find the measure of ∠ 1
a 180°
b 30°
c 60°
d 120°

Answer 1

D. 120 because altogether a triangle equals 180 degrees, so you add 30 and 30 and get 60, then subtract it from 180 and get 120

Answer 2

120 degrees

Explanation:

sum of all three angles of any triangle is 180

X+30+30=180

x+60=180

-60. -60

x=120
