Law of Sines

Used on in a non-right triangle when you have a "pair", which is a angle, and a opposite angle.

The formula is: Sin A/ a = Sin B/ b = Sin C/ c

Cross multiply to solve

You will get two answers for inverse

Check to see if they work or not

#Example 1

Solve

Sin 50/ 25 = Sin 110/a place

aSin50= 25 Sin110 cross multiply

a= 25 Sin 110/ Sin 50 = 30.667 plug into calc

Sin 50/25 = Sin20/c place

cSin50=25Sin20 cross multiply

c= 25Sin20/Sin50 = 11.162
