If equilateral, Y=60, so do the math to find x (=30)

All the angles added together are suppose to equal 180 because theres 180 degress in a triangle.
4/3x+20+4/3x+20+4/3x+20=180
4x+60=180
4x+60-60=180-60
4x=120
4x/4=120/4
x=30
X is equal to 30. Now i dunno which x ur talking about. The X as in angle X in the triangle or the X in the equation for Y. For the equation, X is equal to 30.
X=Y
X=4/3x+20
X=4/3*30+20
X=40+20
X=60
Angle X is equal to 60 degress. *hint hint* never use to of the same variable letters if they're in different position. Oh heres the answers again.
For X in the equation for Y, its 30
For X as in Angle X in the triangle, its 60 degrees.
Mark as best answer. Please and Thank you. =]

60 = 4/3X +20

y = (4/3)x + 20
3((4/3)x + 20) = 180
4x + 60 = 180
4x = 120
x = 30
ANS : 30°

as an algebraic equation
Y = 4/3X +20
Y-20 = 4/3X
3X = 4/(Y-20)
X = (4/3) / (y-20)
