Answer:
Step-by-step explanation:
Factor using Rational Root Theorem.
This means our possible roots are
positve or negative (1,2,3,6). If we try positve 1, it is indeed a root.
This means that
is a root.
We can divide the top equation by the root (x-1). Our new equation is
Now we can factor this completely
So this equation in factored form is

Im guessing this is a rectangle? If so it would be
16+16+25+25
32+50
82 is the perimeter
To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2.
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
