Question

12. In the given figure, find the value of x. Also find the measures of remaining angles. ∆D (2x + 10)° ∆A(3x - 20)°∆B(3x + 10)° ∆C x​

Answer 1

Answer:

∠POR=3x and ∠QOR=2x+10         [ Given ]

POQ is a line.

∴  ∠POR+∠QOR=180o            [ Linear pair ]

⇒  3x+2x+10o=180o

⇒  5x=170o

⇒  x=5170o

⇒  x=34o
