319 in²
Step-by-step explanation:
The applicable area formula is ...
A = 1/2(g)(e)·sin(F)
A = 1/2·(12 in)(55 in)sin(75°) ≈ 319 in²
The area of the triangle is about 319 square inches.

-(1/2)
y1-y2/x1-x2
see below
In decimal, the values of the fractions are ...
-0.2 = -0.200
-3/7 = -0.429
-2/8 = -0.250
So, in a, b, c order, they are ...
a = -3/7
b = -2/8
c = -0.2
56.5
I think this is right
yesss they are
