Question

45
55°
x
Z find the value of x y z​

Answer 1

Step-by-step explanation:

x=180-45+55

x=180-100

×=100°

y=z=40

Answer 2

Answer:

45°+x+55°=180°. (linear pair)

100+x=180°

x=180°-100

x=80°

(opposite angles of equal sides). y=z

x+y+z=180°. (angle sum property)

80°+ a+a=180°

80°+2a=180°

2a=180°-80°

2a=100

a=100/2

a=50

y=z=50°
