Question

a = 16, c = 20, b =

Answer 1

May I help?

Answer 2

sure

Answer 3

Thanks

Answer 4

I am sure that you are familiar with "Law of Cosine".
Are you?

Answer 5

@Danni_joanaveil2
Is the triangle meant to be a right-angled triangle?
If it is, something is missing from the diagram.

Answer 6

ummmm.... no

Answer 7

and yes its a right triangle @mathmate

Answer 8

It states that
\[\frac{ a }{ sinA }=\frac{ b }{ sinB }=\frac{ c }{ \sin }\]

Answer 9

oh okay

Answer 10

So it is mathmate turn!

Answer 11

So the question is really this:

In geometry, what is not given/indicated cannot be assumed.
So missing information will change the problem completely.

Answer 12

yes thats correct

Answer 13

@3mar
Sorry to have butt in. Just wanted to clear up the question.

Answer 14

@mathmate i didn't think it was that important to put the box to indicate it was 90 degrees. i always thought you could just assume.

Answer 15

heres my choices
A) 2√(2)
B) 12
C) 4√(23)
D) 4√(41)

Answer 16

No problem at all, @mathmate!

Nice chance for me and him to know what you are clearing!

Answer 17

:)

Answer 18

so what is Sin?

Answer 19

you mean "Law of Sine"?

Answer 20

yes

Answer 21

It is the law used to solve the triangle in general cases, knowing three given at least!
I think you will study in in advance!

Answer 22

i know cos, sin, and tan. but i dont know what they mean

Answer 23

grade #? if I may know?

Answer 24

im a jr. My freshman and sophomore year i was an idiot and i didn't care about nothing.

Answer 25

mathmate deserves the medal for that question!

Answer 26

i know

Answer 27

You should use the pythagorean theorem
a^2 + b^2 = c^2
