Can someone PLEASE please help me?? i really need it!

Find j.
Write your answer in simplest radical form.

Answer 1

j = 10

Explanation:

use the definition of tangent of an angle:

tan 60 = opp/hyp = (10√3)/j

Solving for j,

j = (10√3)/tan 60

But tan 60 = √3 so we can write j as

j = (10√3)/√3

= 10

Answer 2

10

Explanation:

tan30°=P/B

tan30°=P/10√3

1/√3=P/10√3

1/√3×10√3=P

.:P=10
