Answer 2

Answer:

50, 80, 50 ( since two angles are equal it is an isosceles triangle)

Step-by-step explanation:

The angle sum property of triangle is 180

5x + 8x + 5x = 180

18x = 180

x = 180/18

x= 10

Angle 1 = 5x = 5 multiplied by 10 = 50

Angle 2 = 8x = 8 multiplied by 10 = 80

Angle 3 = 5x = 5 multiplied by 10 = 50

Since two angles are equal it is an isosceles triangle
