Answer:
B 7
Step-by-step explanation:
Since the triangles are similar by AAA
We can use ratios to find the length x (which is PR)
5 15
-------- = ------------
x 21
Using cross products
5 * 21 = 15 *x
Divide each side by 15
5/15 * 21 = 15x/15
1/3 * 21 =x
7 =x
Since they've already told us what triangles are congruent, all we have to do is match up the correct letters.
By CPCTC, angle N is congruent to angle B.

Answer: 7
(I just took the test and it's correct) Hope this helps!
For direct variation y varies directly with x, then we use equation y = kx
Where k is the constant of proportionality
Given: Y equals 2 when X equals 3
We plug in 3 for x and 2 for y and solve for k
y = kx
2 = k(3)
Divide both sides by 3

Now we plug in 2/3 for k

Given x=-0.5 and find out y

y=-0.33
the value of y is -0.33 when x=-0.5
The type of quadrilateral shown is called A kite. The symbols on the sides tell us that two pairs of adjacent sides are equal.
<h3>How to Identify a Quadrilateral?</h3>
A quadrilateral is defined as a closed shape and a type of polygon that has four sides, four vertices and four angles.
Now, from the attached quadrilateral shown, we can say that it is called a Kite. This is because a kite is a quadrilateral that has 2 pairs of equal-length sides and these sides are adjacent to each other.
