Question

PLEASE HELP 


Triangle ABC is a right triangle and sin(53° ) = 4/x. Solve for x and round to the nearest whole number.
     
Which equation correctly uses the value of x to represent the cosine of angle A?
cos(53°) = 4/x
cos(53°) = y/5
cos(53°) = x/4
cos(53°) = 5/y

Answer 1

First, we find x using the given equation:
x = 4 / sin(53)
x = 5

We also know that:
Cos(∅) = base / hypotenuse
Therefore,
cos(53°) = y / 5
