Question

Given: Equilateral Triangle GHJ.

Angle G = 3x; Angle H = 4y; Angle J = 5z.

Find the values of x, y and z.

x =

y =
z =

Answer 1

• x = 20°
• y = 15°
• z = 12°

Explanation:

The measure of each angle in an equilateral triangle is 60°. Divide that value by the coefficient of the variable in the equation:

3x = 60° ⇒ x = 20°

4y = 60° ⇒ y = 15°

5z = 60° ⇒ z = 12°
