Find the value of x. round your answer to the nearest tenth. a.) 52.6 b.) 52.9 c.)

Answers

Option A: 12.5

Step-by-step explanation:

We use trigonometric ratios on this right angled triangle.

$ cos \hspace{1mm} \theta = \frac{adj}{hyp} $

we get:

$ cos \hspace{1mm} 28^{\circ} = \frac{11}{x} $

Also cos 28° = 0.88

Therefore, x = $ \frac{11}{0.88} $

$ = \frac{100}{8}  =\textbf{12.5} $

OPTION A is the answer.

6.2

Step-by-step explanation:

sin 20 = x/18

solve for x

6.2

Step-by-step explanation:

sin 20 = x/18

solve for x
