Question

In triangle ABC, a=6, b=9 and sin A=2/3. Find sin B

Answer 1

wait so a and b are sides?

Answer 2

In general if A is a corner, side a is the side opposite.

Answer 3

but A, B, and C are probably the sides. a, b, and c are probably the angles

Answer 4

If ABC is a triangle, they are the corners/ angles, ALWAYS.

Answer 5

C
/\
a / \ b
/_____\
B c A

Answer 6

C
/\
6 / \ 9
/_____\
B c sin(A) = 2/3 sin(B) = ?????

Answer 7

sin A = a/c
sin B = b/c

sin A = 2/3 so a/c = 2/3 and a = 6 so
2/3 = 6/x
x = 9 so side c = 9

sin B = b/c and b = 9 and c = 9
sin B = 1

I think.....

Answer 8

thats the answer I got

Answer 9

what about this problem: in triangle DEF angle D =40, DE=12 meters and DF=8 meters. Find the area of triangle DEF to the nearest tenth of a square meter
