Answer:

x = 9√3

Explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find x

To find x we use tan

tan∅ = opposite/ adjacent

From the question

The opposite is 9

The adjacent is x

Substitute the values into the above formula

That's


\tan(30) = (9)/(x)


x \tan(30) = 9

Divide both sides by tan 30


x = (9)/( \tan(30) )

We have the final answer as

x = 9√3

Hope this helps you
