degree measure of each angle of a triangle

Question

In the triangle below, suppose that =m∠A+x7°

, =m∠B−6x3°

, and =m∠C4x°

.Find the degree measure of each angle in the triangle.

Answer 1

I changed the wordng like:

In the triangle below, suppose that ∠A = (x + 7)°, ∠B = (6x - 3)°, and ∠C = 4x°. Find the degree measure of each angle in the triangle.

x + 7 + 6x - 3 + 4x = 180

11x = 163

x = 14.8

∠A ≈ 23.8

∠B ≈ 85.9

∠C ≈ 59.3°.
