Question

In the figure shown, what is the value of x?

Answer 1

Explanation:

(6x+10)+(x+17)+(4x+34)=180

11x+61=180

11x+61-161=180-61

11x=119

11x/11=119/11

x=10 9/119

Answer 2

we can see that the triangle is isosceles since it has 2 equal sides

so that means 2 equal angles then :

x + 17 = 4x - 34

3x = 51

x = 17

or

the sum of 3 triangles angles = 180

6x + 10 + x + 17 + 4x - 34 = 180

11x = 187

x = 17
