Question

in this figure, POR and QOR from a linear pair. if x:y =2:3 ,find the value of x and y.​

Answer 1

Since ∠POR and ∠QOR form a ;inear pair.

∴∠QOR+∠POR=180°

⇒x+y=180°.....(1)

Also,

x−y=80°.....(2)(Given)

Adding equation (1)&(2), we have

2x=260°

⇒x=

2

260°

=130°

Substituting the value of x in equation (1), we have

130°+y=180°

⇒y=180°−130°=50

Answer 2

Step-by-step explanation:

x:y=2:3

sum of ratio =2+3=5

X=2/5*180

= 72⁰

y=3/5*180

=108⁰
