Question

In △JKL, what is the length of lineJL?

Answer 1

if someone gives me a formula I can try and solve it, or I could share the multiple choices.

Answer 2

get to know this special triangle and its properties..
this is a 30-60-90 triangle.
propertyies:
-the side opposite the smallest angle is always half of the hypotenuse.
-the other side is (sqrt3)/2*the shoretest side.

that being said, can you figure it out?

Answer 3

Is there a postulate for what you just said? if not then im probably just going get lost in this. I missed out on half of a geometry year sadly.

Answer 4

"-the side opposite the smallest angle is always half of the hypotenuse."*

Answer 5

ok, your smallest side is the 57 right? then JL (the hypotenuse) is twice that big.

Answer 6

ohhh okay, so the Hyp. is 104?

Answer 7

114

Answer 8

careful

Answer 9

oops 114* thank you

Answer 10

np

Answer 11

you actually just helped me out with the whole class. ive needed to know that for so long now. I owe you for passing Geo haha

Answer 12

:)

Answer 13

Does the same rule apply to this problem?
A ladder leans against a house at a 60° angle to the ground. If the ladder extends to a length of 132 inches, what is the height of the house to the nearest hundredth of an inch? (putting a pic in a sec)

Answer 14

yes. in fact, in your higher math classes like trig. you'll get familiar with this triangle a lot. it's not too early to learn it though...

Answer 15

ok thanks!
