Question

Which equation correctly uses the value of x to

represent the cosine of angle A?
O cos(53⁰) =
O cos(53⁰) =
O cos(53⁰) =
O cos (53⁰) = 5
PLEASE HELP

Answer 1

Answer: y/5

Explanation:

5 is the hypotenuse of the triangle and it always goes at the bottom of the fraction. Cosine is the closest two sides to the angle. Giving the answer y/5

Answer 2

Explanation:

For RIGHT triangles ( such as this one) , remember S-O-H-C-A-H-T-O-A .

SinΦ = Opposite LEG / Hypotenuse

Sin (53) = 4/x
