Question

triangles

Answer 1

Solve the triangle.

A = 51°, b = 11, c = 7

Answer 2

hi campbell c:

Answer 3

find a using the law of cosines

\[a^2 = 7^2 + 11^2 - 2 \times 7 \times 11 \times \cos(51)\]

then find the angle B using the law of sines

\[\frac{\sin(B}{11} = \frac{\sin(51)}{a}\]

hope it helps

Answer 4

okay so then a=8.5 C=39 and B= 90 right?

Answer 5

its all makes sense to me
