1) factor to see if you can get anything to cancel out before you multiply
2) the rest of my work is shown in the picture attached
3) the answer is n^2
Answer: 2184
because when you multiply 14 times 12 times 13 you get 2184
They should be both divisible and no decimals
Sine=opposite/hypotenuse
Cosine=adjacent/hypotenuse
Tangent=opposite/adjacent
sinA=16/20=4/5
cosA=12/20=3/5
tanA=16/12=4/3
