Answer:

y=20º

Step-by-step explanation:

RPS+SPM+MPN is 180º

so:

4y-10+90+y=180

simplify

5y+80=180

subtract 80 from both sides

5y=100

divide by 5 on both sides

y=20

Answer:

y = 20

Step-by-step explanation:

line RPN = 180 = 4y - 10 + 90 + y

180 - 90 + 10 = 5y

100 = 5y

y = 100/5

y = 20
