= Value of y:

= y + 70 = 180 ( it is a straight line )

= y = 180 - 70 = 110.

= The exterior angle is equal to the sum of interior opposite angles. Value of x is given by:

= x = 40 + 110 = 150.

Option d.

Verified answer

Answer:

(d) 150°,110°

Step-by-step explanation:

y+70°=180° (Linear Pair are supplementary)

y=180-70=110°

y+40°=x (Exterior angle property)

110°+40°=x

x=150°

∴ x=150° and y=110°
