Remember:
sin²x + cos²x = 1
(-5/13)² + cos²<span>θ = 1
(25/169) + cos²</span><span>θ = 1
cos²</span><span>θ = 1 - (25/169)
cos²</span><span>θ = (144/169)
tan </span>θ > 0 ⇒ cos<span>θ = negative
cos</span>θ = -√(144/169)
cos<span>θ = -(12/13)</span>
To see this, notice that if you remove 25<span> and </span>41<span> from your sequence, then the average of the remaining terms is still given by the average of the extreme terms </span><span><span><span>26+40/</span>2</span>=33</span><span>.</span>
<span><span>
Step 1: Distribute each term of the first polynomial to every term of the
second polynomial. In this case, we need to distribute the 4x and the
–5.

<span>
<span>Step 2: Combine like terms.</span></span></span>
