Question

Find the area of the triangle. We are going to break this one down into steps.
a. Identify which formula to use

Answer 1

fixed

Answer 2

id use law of sines

Answer 3

b/sinB = a/sinA

b = a sinB/sinA
= 42 sin25/sin100

Answer 4

lol, i thought it was find b :) find area eh

Answer 5

lol yea

Answer 6

well

height= b sinC or c sinA

base is given as 42

Answer 7

since b = a sinB/sinC

b sinC = a sinB/sinC * sinC = a sinB

Answer 8

a sinB times a/2 = a^2 sinB/2

Answer 9

\[\frac{42^2~\sin(25)}{2}\]

Answer 10

475.4?

Answer 11

are you in degree mode or radian mode?
