Question

In the given figure OA and OB are opposite rays.

(i) if x = 63° , what is the value of y ? (ii) y = 122° what is the value of x?​

Answer 1

Step-by-step explanation: If x = 63° , then y = ?

x+y = 180°            [ LINEAR PAIR]

=> 63° +y=180°

=> y = 180° - 63°

=> y = 117°

If y=122°  , then x =?

x +y=180                [LINEAR PAIR]

=> x+122° = 180°

=> x=180° - 122°

=> x=58°
