Answer: 24/25 (choice B)

This is because cosine of an angle is the ratio of the adjacent and hypotenuse

So,

cos(angle) = adjacent/hypotenuse

cos(a) = 24/25

--------------

Extra info:

Something like 7/25 would be for the sin(a) value, and 7/24 is tan(a). The reciprocal of 7/24 leads to 24/7, which is the value of cot(a).

Find f(x) and g(x) so the function can be expressed as y = f(g(x)) y = Seven divided by x squared. + 10

Damm [24]

F(x) = 7/x
g(x)=x²+10

Then f(g(x))= 7/(x²+10)

By the way g(f(x))=(7/x)² + 10
