The following problem has been solved for you. Follow it through and master the steps.
Find the area of triangle FGH below:
Step 1
Which formula do we use?
A=1/2absinC
Step 2
Of the three angles, which one will we use?
We will use 500 because it is the angle situated between the two given sides (included angle).
Therefore,
Area= 1/2×6×7sin 500
=16.09cm2
