Question

In the fig, POR = (4y + 2)°, QOR =
(5y-20), find all the four angles.​

Answer 1

Answer:

both angles are 112.2°and 117.5°

Step-by-step explanation:

4y+2+5y-20+4y+2+5y-20=360

18y-36=360

18y=360+36

18y=496

y=496/18=27.5

4×27.5+2=112.2°

5×27.5-20=117.5°

Answer 2

Step-by-step explanation:

(4y+2)+5y-20=180 (linear pair)
