Answer:
root 13 units
Step-by-step explanation:
There is a formula that you use to solve these types of questions.
Given that N is the incenter of △ABC, NS = 4.
<h3>What is the Incenter of a Triangle?</h3>
- The incenter of a triangle is the point of concurrency of the three angle bisectors of a triangle.
- The perpendicular distances from each sides of the triangle to the incenter are equal.
Given the image where:
NQ = 2x
NR = 3x − 2
NQ = NR = NS (equidistant from the incenter)
Thus:
2x = 3x - 2
2x - 3x = -2
-x = -2
x = 2
NQ = NS = 2x
NS = 2(2)
NS = 4
Therefore, given that N is the incenter of △ABC, NS = 4.

Answer:
a = 2.5
b = 4.33
Step-by-step explanation:
a = sin(30 degrees) = o/5 = 2.5
b = cos(30 degrees) = a/5 = (5root3) / 2 or about 4.33
verify using Pythagorean theorem
2.5^2 + 4.33^2 = 5^2
6.25 + 18.75 = 25
25 = 25
Answer:
Step-by-step explanation:
In an arithmetic sequence, we keep adding/subtracting to get the next term in the sequence.
Therefore, we can make an equation that looks like this:
5k-(2k+1) = 7k+2-5k
We can subtract 2k+1 from 5k, and 5k from 7k+2, because from subtracting the difference would be the same. (common difference of sequence is what we would find)
Now, we just need to simplify.
5k-2k-1 = 2k+2
3k-1=2k+2
Now let's combine like terms, and we get:
k=3
