Question

What is the value of y?

Answer 1

Answer:

a

Step-by-step explanation:

1: y+10°+2y+50°=180°

2:3y+60°=180°

3:3y=120°

4:y=40°

Answer 2

Answer:

40°

Step–by–step explanation:

Sum of interior angles in a triangle = 180

:. 2y + y + 10 + 50 = 180

→ 3y + 60 = 180

+60 crosses over, and we have:

3y = 180 — 60 → 3y = 120

At this juncture, we divide by the coefficient of y, as shown below↓

$\frac{3y}{3} = \frac{120}{3}$

Then, we have:

$\frac{120}{3} = 40$

:. 40° is our final answer.
