Find the measure of b, given m 11 years ago

Answer 1

Answer 2

The law of sine states \[\large \frac{\sin(A)}{a} = \frac{\sin(B)}{b} = \frac{\sin(C)}{c}\] where A B and C are the angles given..and a b and c are the side lengths

Answer 3

well the law of sine is

\[\frac{a}{\sin(A)} = \frac{b}{\sin(B)}\]

so substitute your information and then solve for a

hope it helps

Answer 4

if we know \[\large \frac{\sin(A)}{a} = \frac{\sin(38)}{31}\]
and \[\large \frac{\sin(B)}{b} = \frac{\sin(74)}{b}\]

we then know

\[\large \frac{\sin(38)}{31} = \frac{\sin(74)}{b}\]

and we can solve for 'b'

Answer 5

18.3?

Answer 6

Hmm..not quite what I get...

Rearranging that equation we have

\[\large b = \frac{31\sin(74)}{\sin(38)} = ?\]

Answer 7

now my calc says 37.8

Answer 8

Hmm still not what I'm getting..I receive an answer of

\[\large 48.4\]

Answer 9

Oh that's weird

Answer 10

okay thanks!

Answer 11

No problem :)

Answer 12

Is your calculator in the wrong mode!? If it is in radians and it needs to be in degrees, your answer will be WAYYYYY off!!! Check that and try again

Answer 13

My calculator?
