Question

A Find the value of x. Your answer must be exact. 30 9

Answer 1

Tan30=9/x so it will be 9((3)^1/2)

Answer 2

Answer:

x = 9√3

Step-by-step 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

$\tan(30) = \frac{9}{x}$

$x \tan(30) = 9$

Divide both sides by tan 30

$x = \frac{9}{ \tan(30) }$

We have the final answer as

x = 9√3

Hope this helps you
