Which equation can be used to find the unknow ange measures?

The diagram is a triganle. A= x+30, B= 3x, and C = x-15

A 5x+15=90
B 5x+45-180
C 3x^3+15=180
D 5x+15=180
E 3x+30=180

Assuming A, B, and C are the angles, then

x+30 + 3x + x-15 = 180
5x + 15 = 180

measures of a triangle. m<a=(x+30) m<b=x M<c=(x+60) so then would i set up the problem as x+30+x+x+60=180 and then would i combine like terms so i get 30+x+60=180 and then 30-60=30 so then 180/30=6 so x=6
