Answer 1

Answer:

x=52

Step-by-step explanation:

since its an isosceles triangle, both sides are to have the same length.

so x+10+x+10+3x=180(all angles added in a triangle gives 180)

5x+20=180

5x=180-20

5x=160

x=160/5

x=52

Answer 2

All triangle have 180 degree
isosceles = 2 equal angle
x + 10 + x + 10 + 3x = 180
5x + 20 = 180
5x = 160, x = 32
Plug in 32 for angle U
3(32) = 96
Solution: angle U = 96 degrees
