Question

20. Observe the following figure, find the values of the angles x, y, z.
у
45
Х
Z​

Answer 1

Step-by-step explanation:

Y=45(given),x=y(xyz is an isoceles triangle)

to find x and y

y+x+z=180(angle sum property of triangle)

45+2x=180(take z=x )

2x=180-45

x=135/2

x=67.5

so x=z=67.5 is the answer
