sin(C). She knows the area of a triangle is 1/2 times the base times the height, so here, A=
2
Myra needs to set up a sine ratio: sin A =
Myra needs to set up a sine ratio: sin C =
Myra needs to set up a sine ratio: sin C =
h<
b>c
a<
b>h
h<
b>a
Myra needs to set up the sine ratios: sin C =
and then solve for h.
and then solve for h.
and then solve for h.
h<
b>a
and sin A =
h<
b>c
Solve for h in both equations
