x and y are two supplementary angles such that y is 4 times as large as x. Find the value of x

Question

remember that x and y are supplementary.

Answer 1

y = 4x

x + y = 180

x +4x= 180

5x = 180

x = 180/5

x = 36

y = 4 • 36

y = 144

Answer 2

Remember X is y is Supplementary and supplementary angles add up to 180 degrees.

1. You set up the first equation

y=4x

2.You set up the second equation by substituting for y

x+4x=180

5x=180

__ __

5. 5

x=36

Then you divide both sides of the equation the solution should turn out to be 36.

ANS: x=36

Answer 3

y = 4x

x + y = 180°

x + 4x = 180°

Can you solve for x and answer?
