The cosine of B = 4/5 so the adjacent side divided by the hypotenuse = .8
So 10/.8 = 12.5 the length of the hypotenuse

Help! find g(x)-f(x) if f(x)=-3x+4 and g(c) =5x-12

Marianna [84]

Replace f(x) and g(x) with what they equal:

$5x - 12 - (-3x + 4)$
$5x - 12 + 3x - 4$

Combine like terms:

$5x + 3x = 8x$
$-12 - 4 = -16$

$8x - 16$

The answer is C.
