Question

PLEASE HELP: 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 PLEASE HELP: 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 @Mathematics

Answer 1

Use the laws of sine
\[a/sinA=b/sinB\]
To find Angle B.
Then 180 degrees -140 degrees - angle B will give you Angle C.
Then use laws of sine to find
side c
\[c/sinC=b/sinB\]
