Question

cant figure out this problem... right triangle

Answer 1

you can you use the Sine Law since you know an angle and the corresponding side (the right angle is a known measure):
\[\frac{\sin C}{c}=\frac{\sin A}{a}\]

Answer 2

i have no clue what im doing XD

Answer 3

you should start with what you know:
1. All the side lengths
2. One angle

With this information you are able to use the Sine Law. The Sine Law is basically this:
In any triangle, the ratios of the Sine of each angle to its corresponding side length is equivalent.
Another way of saying this is:
As the angle within a triangle increase, so to does the side length.


-You are asked to solve sin(C)
-plug the values that are given in the picture into the equation above and solve sin(C)
(ie plug and play)

Answer 4

alright i get it now. now its timeto figure itout

Answer 5

let me know how your making out after you give it a go

Answer 6

i got the answer as 0.4 and after you explained it was pretty easy

Answer 7

right.
If they were asking for the actual angle of c would you know how to solve that?

Answer 8

no probably not

Answer 9

well, look into it, you'll need to know it very soon

Answer 10

alright i will
