Question

If B = 140◦, a = 64, b = 12, solve the triangle. (If there is no solution, give −1 as your answer.)
a) Find A. (If there is more than one
solution, give the larger one.)

b) Find the corresponding angle C

c) Find the corresponding side c If B = 140◦, a = 64, b = 12, solve the triangle. (If there is no solution, give −1 as your answer.)
a) Find A. (If there is more than one

b) Find the corresponding angle C

c) Find the corresponding side c @Mathematics

Answer 1

sin140/12=sinA/64
sinA = 64(sin140)/12
sinA = 3.43
This is impossible since the sin cannot be greater than 1. Therefore there is no solution so give -1 as your answer.

Answer 2

for part b or c?
