Question

The longer leg of a 30°-60°-90° triangle is 18. What is the length of the other leg?

Any help please?

Answer 1

The shortest leg would be 9

Answer 2

The other leg would equal (square root of three / 2) * 18
15.5884572681
or about 15.588

Answer 3

but if the shortest leg were 9 then hypotenuse would be 18 and the hypotenuse cant be the same at the leg

Answer 4

Shortest leg = 9
"Medium" side = 15.588
Hypotenuse = 18
Where's the problem?

Answer 5

cause isnt the question giving the medium? it didnt say the hypotenuse was 18 is said the longest leg was 18

Answer 6

Okay, technically, the"leg" of a right triangle is generally not the hypotenuse.

I wish they would word these problems better.

The "longer leg" = 18

When you know the "medium" side then the short leg =
"medium" side * (1/square root of 3) =
10.3932

Answer 7

its gives me 4 answers
A 4(square root over 3)
B) 12(square root over 3)
C) 9
D) 6(square root over 3)

Answer 8

It seems 9 is the only correct answer IF the hypotenuse is equal to 18.

Answer 9

alright ill give 9 a try thank you

Answer 10

Will you get an answer right after you post that?

Answer 11

no not right away but i am kinda of question that but you are smarter then me so ill take that answer

Answer 12

Well thanks for the comment. Well maybe in math anyway.

Answer 13

ha yeah thank you

Answer 14

okay and good luck.

Answer 15

@mathmath333 are you good at geometry? if so im having trouble with this question and im questioning the answer he gave me which was 9 could you possibly help me a bit?

Answer 16

help im questioning the answer 9?

Answer 17

is it right @zepdrix

Answer 18

how did you conclude that 18 was the hypotenuse? isnt the longest leg 18 like i told him its not saying the hypotenuse is 18 is saying the longest leg is 18 so were already given 1 leg

Answer 19

oh oh oh oh oh,
when i read the question, for some reason i read "longest leg"
it says longer leg, woops woops woops :)
