Question

Can someone explain how to solve this, equations aren’t my stronghold

Answer 1

Answer: y=-33.25 or -33.3

Explanation:

2x=88

x=44

the triangle has 180 total angle

4y+(5x+5)+2x=180

substituting the numbers

4y+(5(44)+5)+2(44)=180

4y+(220+5)+88=180

4y+225+88=180

4y+313=180

(-313)

4y=-133

(divide by 4)

y=-33.25 or -33.3
