Answer:
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.
5/10+2/9=13/18
=1/2+2/9
=9/18+4/18
=9+4/18
answer: 13/18
-10
I dont really understand the question but I think its -7.
