Question

SEE IMAGE! Which of the following expressions is equal to the value of x?

A) 0.9(sin50)
B) (sin50)/0.9
C) 0.9(cos50)
D) (cos50)/0.9

Answer 1

A) 0.9(sin50)

Explanation:

Since this is a right triangle, we can use

sin a = opposite side/ hypotenuse

sin 50 = x /.9

Multiply each side by .9

.9 * sin 50 = x/.9 * .9

.9 (sin 50) = x
