Question

Find the value of x and y.
Solution x= and y=

Answer 1

First :

(y+5)=(2x+7) vertically opposite angles

So then :

(X+1)+(2x+7)+(x-4)=180 angles on a straight line

X+2x+X=180-1-7+4

4x=176

divide both sides by 4

X= 44

now sub it in:

(X+1)+(y+5)+(x-4)=180 angles on a straight line

44+1+y+5+44-4=180

y=180-44-1-5-44+4

y=90
