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

Answer:

• x = 20°
• y = 15°
• z = 12°

Step-by-step 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°
