Question

help only question no. 4​

Answer 1

Answer:

let angle POR be 5x and ROQ be 7x

then 5x+7x=180. (linear pair)

12x=180

x=180/12

x=50/3

SOQ=POR

SOQ=5x

=5×50/3

hope it helps

please mark as branliest

Answer 2

as angle por + angle roq =180

so let the common ratio be x then.

5x+7x=¹⁸⁰

then 12x=180

x=180/12

so angle por is 180/12×5= 75

then as angle por= anglesoq

so angle soq is 75⁰
