Question

Solve the following triangles. If the answer isnt a whole number, round to the hundreths place
1. A=60 degrees, a=1, b=2
I NEED HELP!!

Answer 1

I dont see a diagram, but I'm assuming A is the angle in between a and b. So use
Area = 0.5 x a x b x Sin 60

Answer 2

do you need the area?

Answer 3

no I just have to find angle B, Angle C and side c

Answer 4

Use the Sine and Cosine rules

Answer 5

Law of sines is what we are doing

Answer 6

the law of sine says

\[\frac{\sin(60)}{1} = \frac{\sin(B)}{2}\]

solve for B

then use angle sum of a triangle to find C

then use the law of sine again

\[\frac{1}{\sin(60)} = \frac{c}{\sin(C)}\]

hope it helps
