Hello!
As you can see, the angles we are given make up a 90 degree angle. We have the equation below.
4x=90
To solve we just divide both sides by 4.
90/4=22.5
x=22.5
I hope this helps!
Answer:
volume of a triangular prism: use the equation V = ½ × length × width × height, or V = the area of the base × the height and that might work with many shapes. Find the area of the base: ½ × the length and width then locate the height, and multiply the height by the area of the base.
Step-by-step explanation:

Applying the centroid theorem, the length of QR is: 12.
<h3>What is the Centroid Theorem?</h3>
- According to the centroid theorem, the centroid (the point where the three medians intersect) is 2/3 of the distance from the midpoint of the a side to each vertex opposite vertex of the triangle.
Given:
QU = 8
QU = 2/3(QR)
8 = 2/3(QR)
3(8) = 2(QR)
24 = 2(QR)
QR = 12
Therefore, applying the centroid theorem, the length of QR is: 12.

Answer:
Paula's mother received $654.75 for the dress.
Step-by-step explanation:
Identify what you know:
1) Paula's mother sold a prom dress listed at $675.
2) Paula's mother receives 97% of the sale, after paying the 3% credit card fee.
Whenever calculating the percentage of something, you can use an easy formula:
% times number = x
For instance:
97% x $675.00 = $654.75
We can calculate how much the credit card fee is too!
3% x $675.00 = $20.25
1 80/333 is about 1.24
the full decimal is 1.24024024... etc
