Question

lines and angles pls help​

Answer 1

Answer:

x = y = z = 45

Step-by-step explanation:

as given in 45degrees and y are vertically opposite angles. They must be equal. so,

-> y = 45.

Now,

As sum of all angles = 180

x + y + z + 45 = 180

x + 45 + z + 45 = 180

x + z + 90 = 180

x + z = 180 -90 = 90

As, we know that, x and z are vertically opposite angles, they must be equal. such that

x = z = 90/2 = 45 .......
