Question

Given: A ABC
The measure of measure of

Answer 1

∠A = 90

∠B = 30

∠C = 60

Explanation:

Let ∠B = x

∠A = 3x

∠C = x + 30

Angle sum property of triangle: Sum of three angles of triangle is 180

x + 3x + x + 30 = 180 {Combine like terms}

5x + 30 = 180

5x = 180 - 30

5x = 150

x = 130/5

x = 30

∠A = 3*30 = 90

∠C = 30 + 30 = 60
