Question

please show work. Use a trigonometric function to find the value of x. (Round your answer to the nearest tenth).​

Answer 1

x = 12.2

Explanation:

sin theta = opp / hypotenuse

sin 55 = 10 /x

Multiply each side by x

x sin 55 = 10

Divide each side by sin 55

x = 10 / sin 55

x =12.20774589

Rounding to the nearest tenth

x = 12.2
