Question

7. Find the values of the unknown angles x, y and z in the given figure.​

Answer 1

Answer:

X=180-(100+25)=55°

X+y=180

55+y=180

y=180-55

y=125°

z=20+y(exterior angle property)

z=20+125

z=145°

Answer 2

Answer:

x=180-(100+25)=55°

x+y=180°

55°+y=180°

y=180°-55°

y=125°

z=20°+y(exterior angle property)

z=20°+125°

z=145°.

This is the answer.
