Question

2. Find the measures of x, y and z in the figure where l || AC.
​

Answer 1

Answer:

z = 55 ( alternate angle )

x = 65 (alternate angle )

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

y = 180 - 120

y = 60

Answer 2

Answer:

A= 65°

C= 55°

we know,

A+y+C =180

55+y+65 =180

120 + y = 180

y= 180 - 120

y= 60

(x=A = 65

z= B =55)alternative interior angles
