The answer is C. 45. Here's the work to prove it: c = correct answer, i = incorrect answer;

-2(c + i = 50)

2c - 3i = 75

-2c - 2i = -100

-5i/-5 = -25/-5

i = 5

c + 5 - 5 = 50 - 5

c = 45

20F - 18F = 1/4x24
2F = 6
F = 6/2

Answer:

Step-by-step explanation:

Since tan(x) = sin(x)/cos(x), if sin(x) = cos(x) then tan(x) must be 1.

You can even reason that the acute angle is 45° and sin(x)=cos(x) = $\frac12\sqrt2$ .
