The perimeter is 30 for this answer I just did this yesterday. What you do is look at the top of the triangle the other side of where 6 is at is congruent and you do the same for 4 and 5
<span> graph of y = [x] for -2 ≤ x ≤ 2 </span>
? What do u need help with? I would be glad to help but there isn’t enough explanation!
Answer:
what we have to find , please complete the question
Answer:
Step-by-step explanation:
use the formula { a couple of times} cos 2 Θ = 2 cos ² Θ - 1 = 1 - 2 sin ² Θ....your answer will likely have a cos 2x , a cos 4x , and a cos 6x in it.....note : cos ² Θ - sin ²Φ = cos ( Θ + Φ) cos (Θ - Φ) will also be needed for appropriate choices of Θ & Φ in terms of x
