Find value of angle 1, 2, and 3, where angle y is equal to angle 3a)60...
Adding both sides, we have:
∠y + ∠1 + ∠2 = 3∠x
∠y + ∠1 + ∠2 = 3∠x
Therefore, 180° = 3∠x (Angle sum property of a triangle)
So,∠x = 180° ÷ 3 = 60°
∠x = 60°, ∠y = 60°
Therefore, the value of all angles is 60° and it is an equilateral triangle
Therefore, the value of all angles is 60° and it is an equilateral triangle
