Answer:
<h2>a perfect square trinomial</h2>Step-by-step explanation:
The given expression is
As you can observe this is a binomial expression under a square power. Additionally, this is a special product, which equivalent expression is a perfect square trinomial, because from this square power we get two perfect square and one linear term.
Therefore, the right answer is B.
Let's solve the expression to demonstrate what we said before
As you can observe, the expression is equivalen to a trinomial.

Answer:
Arc length MK = 15.45 units (nearest hundredth)
Arc measure = 58.24°
Step-by-step explanation:
Calculate the measure of the angle KLN (as this equals m∠KLM which is the measure of arc MK)
ΔKNL is a right triangle, so we can use the cos trig ratio to find ∠KLM:
where:
is the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- A = LN = 8
- H = KL = 15.2
Therefore, the measure of arc MK = 58.24° (nearest hundredth)
Given:
- r = 15.2
- ∠KLM = 58.24313614°
