Suppose that triangle tuv is an isosceles with the base vu. suppose also that angle v=(3x+39) and angle u=(4x+34) . find the degree of each angle in the triangle.

Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72
