Question

Determine the value of x using a trigonometric ratio.

A) 10.11 units
B) 4.98 units
C) 4.18 units
D) 8.49 units

Answer 1

b

Explanation:

Answer 2

We have a known hypotenuse, but unknown opposite side. Use the sine ratio to tie the two together to be able to solve for x.

sin(angle) = opposite/hypotenuse

sin(50) = x/6.5

6.5*sin(50) = x

x = 6.5*sin(50)

x = 4.97928888027336 make sure your calculator is in degree mode

x = 4.98

Answer is choice B
