Question

Find the value of x :)))))

Answer 1

Answer:

A x =30

Step-by-step explanation:

(y+x)  and (y-x)  make a straight line so they add to 180 degrees

(y+x)  + (y-x) = 180

Combine like terms

y+y+x-x=180

2y=180

Divide by 2

2y/2 = 180/2

y= 90

(y+x)  and 2x  make a straight line so they add to 180 degrees

y+x+2x = 180

Combine like terms

y+3x = 180

Since we know y we can substitute it in

90+3x = 180

Subtract 90 from each side

90-90+3x= 180-90

3x = 90

Divide by 3

3x/3 = 90/3

x= 30
