Question

Find the values of x and y.

Answer 1

4y+112=180 angle sum property
Therefore,
4y=180-112
= 68
As 4y=68 then y = 17

Now,
4y +7x+7=180 angle sum property
7x =180-68-7
7x=105
X=15

Answer 2

7x + 7 = 112

-7

7x = 105

divide 7

x = 15

Now, for y.

Angle 112 and the unknown angle = 180*

This means the unknown angle = 68

4y = 68

divide 4

y = 17
