First, you would move the decimal place two places to the right. Then that would be your answer. For this case, the answer would be 250%.

To express any number as a decimal, just multiply it by 100 .

Often, an easy way to do that is to move the decimal point
two places to the right.

2.50 = <em>250%</em>

Abby used the law of cosines for TriangleKMN to solve for k.

Answer:

m∠K = 37° and n = 31

Step-by-step explanation:

A lot of math is about matching patterns. Here, the two patterns we want to match are different versions of the same Law of Cosines relation:

a² = b² +c² -2bc·cos(A)
k² = 31² +53² -2·31·53·cos(37°)

<h3>Comparison</h3>

Comparing the two equations, we note these correspondences:

a = k
b = 31
c = 53
A = 37°

Comparing these values to the given information, we see that ...

KN = c = 53 . . . . . . . . . . matching values 53
NM = a = k . . . . . . . . . . . matching values k
KM = b = n = 31 . . . . . . . matching values 31
∠K = ∠A = 37° . . . . . . . matching side/angle names

Abby apparently knew that ∠K = 37° and n = 31.

<em>Additional comment</em>

Side and angle naming for the Law of Sines and the Law of Cosines are as follows. The vertices of the triangle are labeled with single upper-case letters. The side opposite is labeled with the same lower-case letter, or with the two vertices at either end.

Vertex and angle K are opposite side k, also called side NM in this triangle.
