Question

In △JKL, what is the length of line segment KL?

11.5

23radical 2

46

23radical 3

Answer 1

first using def of cos we have JL= KJcos60 = 23* 1/2= 11.5

and then KL= \[\sqrt{JL ^{2}-JK ^{2}}\]

u can substitute and go..... the answer!!!!!!

Answer 2

so the answer is 11.5

Answer 3

nope this is the same special triangle, so the answer involves \(\sqrt{3}\)

Answer 4

30-60-90 triangle :

◦The length of the side opposite the 60 degree angle is found by multiplying the length of the side opposite the 30 degree angle by \(\sqrt{3}\)

Answer 5

23 sqrt 3

Answer 6

thats right!

you can solve these by using soh-cah-toa as @sriramkumar hinted.. .
