Answer:
Area = 1/2ab sinc
Step-by-step explanation:
the area is given by two sides subtending an angle directly opposite a third side
First you need to solve for angle F then you can use 1/2acSinB. If you haven't done this you can also use the Pythagoras theorem and solve for the unknown side once you do that you can just use 1/2 b*h
The think the answer for number 7 is A/10
Number 8 is C/16
