Question

The measure of the 3 angles in a triangle are (4x) degrees,(3x-3) degrees, and (5x+3)degrees. Please write an equation, solve for x, and determine the measure of each angle. Please show work and thanks for helping

Answer 1

This is a good one!

So we know that a triangle's angles must add up to 180 degrees. Therefore, we can say that:

(3x - 3) + (5x + 3) + (4x) = 180.

This can be rewritten as 12x = 180.

Divide each side by 12 to get x alone, you get:

x = 15

Time to plug n' chug.

4x = 60, 3x - 3 = 42, 5x + 3 = 78

Boom!
