<span>x² + 20x = 52.  Why?  Completing the square is easier for this equation in comparison to completing the square for the first two equations.

x^2-8=1 becomes x^2=9, so that x=plus or minus 3.  Why bother with completing the square here?

x^2 + 20x                          = 52
x^2 + 20x + 100 - 100       = 52
       (x+10)^2                    = 152

taking the sqrt of both sides:

x+10 = plus or minus sqrt(152)    (and so on).</span>

Answer: C.

Step-by-step explanation:

An isosceles triangle is a type of triangle that has two identical sides and angle measures. Knowing that the two sides creating the 44 degree angle are equal, you can also know that both remaining angles are equal.

All three angles in a triangle must add to 180, so you can solve for f through this equation:

2f + 44 = 180

2f = 136

f = 68
