the question says determine the area of the triangle...
im going to try to explain how the triangle looks like...
angle A is 32 degrees.
angle B is 50 degrees.
angle C is 98 degrees.
Disatance from A to C is 10
A to B = 12
C to B = 7
when i worked it out i got 32.171.... is that right?

I dropped the perpendicular from C to side AB (makes a 90 degree angle with AB).
This I will call the height (h) knowing that the area is one half of base*height. Here AB is my base.
h/7 = Sin(B)
h = 7*Sin(50) = 5.3623
Area =
0.5*AB*h = 0.5*12*5.3623 = 32.174...

area of a triangle, is
0.5 X a X b X Sin C
so "35 X sin98 "= 34.65
