Question

In the following figures, find the values of x and y.​

Answer 1

40+170+X=180.

(triangle sum property)

X = 180-210

X = -30

to find y......

we know that....

X + 65 + y = 180

(sum of the angle of semicircle is 180)

-30+65+y= 180

35 + y = 180

y = 180-35

y= 145°

hope this will help you
