Question

9) Find the value of x and y

Answer 1

Explanation:

Let’s start with y.

Because they are opposite angles on 2 180 degrees lines 102 = y-17

Now solve

102 = y - 17

Now add 17 to both sides

119 = y

For x

Because it is on a 180 degree line

102 + 3x = 180

Now subtract 102 from both sides

3x = 78

Now divide each side by 3 to get x alone

x = 26

This proves the answer is in fact A
