Step-by-step explanation:

Remark

The two angles with x in them are = 90 degrees. That's because this is a right angle triangle.

Equation

x^2 + 10x + 115 = 90               Subtract 90 from both sides

Solution for x

x^2 + 10x + 115 - 90 = 0

x^2 + 10x + 25 = 0

Factor

(x + 5)(x + 5) = 0

x = - 5

Angle C

C = 10x + 115

C = 10*-5 + 115

C = -50 + 115

C = 65

Angle A (which you don't need)

x^2 = (-5)^2

x^2 = A = 25

Find BC

Cos(C) = adjacent / hypotenuse

Cos(65) =0.4226

AC = hypotenuse = 65

0.4226 = adjacent / 44   Multiply both sides by 44

44 * 0.4226 = adjacent

adjacent = 18.6 to three places.
