Question

Find x y z . Prove Your Answer​

Answer 1

Step-by-step explanation:

Let the names of all angels be x

We know that,

Sum of any quadrilateral is 360°

so,

x + x + x+ 80° = 360°

3x + 80° = 360°

3x =. 360° - 80°

3x. =. 280

x = 280÷3

x =. 90.33

Answer 2

Step-by-step explanation:

y=z

y=80°(vertically opposite angle)

y=z=80°

x=180°-80°(linear pair)

x=100°
