Question

In the given figure, ∟POR and ∟QOR form a linear pair if a - b=80 º then values of a and b respectively are:

Answer 1

Answer:

a = 130°; b = 50°

Step-by-step explanation:

∠POR = a

∠QOR = b

∠POR + ∠QOR = 180° (Given)

⇒ a + b = 180° (i)

a - b = 80° (Given) (ii)

Using elimination method,

   a + b = 180°

+  a  - b =  80°  

       2a = 260°

         a =  130°

a - b = 80°

⇒ 130° - b = 80°

⇒ b = 50°
