Solve for x. enter your answer in the box. x =

So this is an equilateral triangle
meaning all the sides are the same and equal to 180
Each angle equals 60°
to solve
2y = 25x - 15
180 = 25x - 15 + 25x -15 + 60 
combine like terms
180 = 50x -30 + 60
180 = 50x + 30
subtract 30 from both sides
150 = 50x
divide both sides by 50
3 = x

now plug into the original problem
2y = 25x - 15
2y = 25(3) - 15
solve
2y = 75 - 15
2y = 60
divide both sides by 2
y = 30

Hope this helps :)
