2x+2x+(x-15)=180
4x+x-15=180
5x=180+15
5x=195
x=195/5
x=39

Answer:

x = 39

Step-by-step explanation:

Its an isosceles triangle, so,

angle A = angle C = 2x

Sum of angles in a triangle = 180, which is why when you add x - 15 , 2x and 2x its equal to 180.

Now you have a linear equation. Solve it to find the value of x.
