Question

Use the given information to solve the triangle for A = 150°, b = 4.8, a = 9.4

Answer 1

Well you can start by drawing a triangle with the information

the size of angle B can be found using the Law of Sine


`(sin(150))/(9.4)) = (sin(B))/(4.8)`

the size of angle C can be found using angle sum of a triangle.

The length of side c can be found using the Law of Cosines


`c^2 = 4.8^2 + 9.4^2 - 2 *4.8*9.4* cos(C)`

hope it helps
