Answer:

the answer is 13.5

Step-by-step explanation:

A=105

B=4

C=7

so you just plug in using the trigonometric formula for area which in this case would be

1/2(4)(7)sin(105)

then you just type that into a graphing calculator (make sure its set to degrees) then you get 13.52 which would be 13.5 rounded.
