write your answer in simplest radical form.
(square) feet
submit
work it out

Explanation:

Step1: Use tangent definition

$\tan(60^\circ) = \frac{j}{3\sqrt{3}}$

Step2: Substitute $\tan(60^\circ)=\sqrt{3}$

$\sqrt{3} = \frac{j}{3\sqrt{3}}$

Step3: Solve for $j$

$j = \sqrt{3} \times 3\sqrt{3} = 3 \times 3 = 9$

Answer:

9 feet
