Question

Q.8. Given POR = 3x° and QOR = (2x + 30°, find
the value of x for which POQ is a straight line.
​

Answer 1

Answer:

Answer

Correct option is

A

34

∘

∠POR=3x and ∠QOR=2x+10 [ Given ]

POQ is a line.

∴ ∠POR+∠QOR=180

o

[ Linear pair ]

⇒ 3x+2x+10

o

=180

o

⇒ 5x=170

o

⇒ x=

5

170

o

⇒ x=34

o

Answer 2

Step-by-step explanation:

< POR= 3x°

< QOR=(2x+30)°

=> 3x +2x+30 = 180°_ _ _ _ [straight angle]

=>5x +30 = 180°

=> 5x= 180–30

=> 5x= 150

=> x= 150/5 = 30

The value of x =30 .
