Question

Precalculus- Law of sines help!!
Look at picture below!

Answer 1

Well, do you know the law of sines?

Answer 2

Yes

Answer 3

\(\sf \frac{A}{sin(a)} = \frac{B}{sin(b)} =\frac{C}{sin(c)} \)

Answer 4

I already did it but I could be wrong

Answer 5

I did: sin38/10=sinA/19

Answer 6

sin A = (19)(sin 38)/(10) = 1.17

Answer 7

the calculations appear correct... so what do you know about

sin(A) = 1.17..

Answer 8

that it is not possible

Answer 9

because that would give a sin A that is greater than 1 and that is impossible.

Answer 10

I am stuck between choice A and D,,,

Answer 11

ok....well you are on the right track...



looking at the sine curve the max and minimum values for sign lie between -1 and 1.

you have a value that is outside this range... so it doesn't exist... so no triangle is formed because the angle doesn't exist
