Select one:
a. 28.5
b. 22.4
c. 25.8
d. 24.2

Answer 2

Do you know the law of sines?

Answer 3

Kind of.

Answer 4

They simply state that a/SinA = b/SinB = c/SinC

Answer 5

Alright.

Answer 6

You could use the law of sines.
\[\frac{ \sin93 }{ 25 }=\frac{ \sin75 }{ y }\] If not there are other ways to find it.

Answer 7

This can be used with the known x values to find the y value

Answer 8

@wrstlr3232 One of us has the fractions upside down :P

Answer 9

Haha, well you can use it the same way. As long as you have sin in the same place.

The proportion that you had gave 24.148 would I round that up to 24.2 then to fit D? Or did I do something wrong?
