Question

Solve the triangle. Round lengths to the nearest tenth and angle measures to the nearest degree.

b = 4, c = 6, A = 85°

Answer 1

Use the Law of Cosines

a^2 = b^2 + c^2 - 2bc * cos(A)

Once you have a, you can use the Law of Sines:

a/(sin(85)) = b/sinB = c/sinC

Answer 2

Do you have any other questions?

Answer 3

thats not any of the answers they have up there sorry .

Answer 4

This is HOW to do it. Not the answer O.o
