Question

Can someone help me with this problem and explain it

Answer 1

Answer:

A. 30 - y.

Step-by-step explanation:

< GLQ = 180 - 30 = 150.

So  < z + <LGQ = 180 - 150 = 30.

< LGQ = < y (opposite angles)

So  z + y = 30

So z = 30 - y.

Answer 2

Good evening ,

______

Answer:

z = 30 - y

____________________

Step-by-step explanation:

x=180-30=150

z+x+y=180

Then

z=180-(x+y)

=180-(150+y)

=180-150-y

=(180-150)-y

=30-y.
