Question

PLEASE HELP: If a = 4, b = 16, c = 4.5, solve the triangle. (If there is no solution, give −1 as your
answer.)
a) Find C. (If there is more than one
solution, give the larger one.)

b) Find the corresponding angle A

c) Find the corresponding angle B

Answer 1

cos B = (b^2-a^2-c^2)/-2ac
cosB = (256-16-20.25)/-36
cosB = -6.1
Not possible. cosine cannot be smaller than -1 So the answer is -1
