Question

Need someone to double check this one.
In △JKL, what is the length of KL?

Answer 1

Answer choices:
11.5
\[23\sqrt{2}\]
46 (this is my choice)
\[23\sqrt{3}\]

Answer 2

kl=23/tan30

Answer 3

In a 30-60-90 triangle the longer leg is equal to the shorter leg times sqrt 3

Answer 4

ok

Answer 5

So you are saying the last answer is correct

Answer 6

Yes.

Answer 7

Ok thank you. :)

Answer 8

It is a good thing to memorize the relationships in a 30-60-90 rt triangle. The hypotenuse is twice the length of the shorter leg, and the longer leg is sqrt 3 times the shorter. That allows you to derive the six trig functions for 10 and 60 degrees.
