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.
Answer:
64
Step-by-step explanation:
115 - 51 = 64
First off, turn 7 1/4 into a mixed number, 29/4. change 29/4 / 5/6 into a multiplication question by flipping 5/6 into 6/5 (AKA multiplying by the reciprocal) so you get 29/4 X 6/5. then multiply so you get 174/20. Next, simplify into a mixed number by seeing how many times 20 goes into 174, and then putting the leftovers into a fraction, so you get 8 14/20, then simplify even further so you get 8 7/10.
What's the percentages?? I need to know that first
