Question

Write an equation and solve for x.

Answer 1

x = 22

Explanation:

All the sides are equal. So, it is and equilateral triangle and so all the angles will be equal.

Each angle of equilateral angle = 180/3 = 60

3x - 6 = 60 {Add 6 to both sides}

3x = 60 +6

3x = 66 {Divide both sides by 3}

x = 66/3

x = 22
