pls brainlyest
First factor out a variable: x(x^2-2x-24)
now solve the quadratic: x(x-6)(x+4)
When you set these expressions equal to zero, you get 0, 6, and -4 as your answers.


therefore~

therefore the measure of all the angles are..
∠1 = 63°
∠2 = ( x + 17 ) = ( 21 + 17 ) = 38°
∠3 = ( 4x - 5 ) = ( 84 - 5 ) = 79°
