Question

In the figure, find the value of
x , y
​

Answer 1

Answer:

In triangle ABC three angles = to 180 °

so 180 - 40= 140

so 140 / 2= 70

Angle B equal to 70 and angle C equal to 70

In a small triangle three angles = 180°

one angle is 140°

so 180° -140°=40

so x= 20 and opposite of x = 20

Therefore angle x= 20

angle y =70
