Find the measure of the indicated angle the answer should be 59 show steps

measurement of the indicated angle is 59°

Step-by-step explanation:

20x - 19 + 8x + 3 = 180

28x - 16 = 180

+16 +16

28x = 196

28 28

x = 7

8 (7) + 3 = 59

20 (7) - 19 = 121

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
