Answer:
5.1
Step-by-step explanation:
![tan \ 25 = \frac{opposite \ side}{adjacen \ side}\\\\tan \ 25 =\frac{x}{11}\\\\0.4663 =\frac{x}{11}](https://tex.z-dn.net/?f=tan%20%5C%2025%20%3D%20%5Cfrac%7Bopposite%20%5C%20side%7D%7Badjacen%20%5C%20side%7D%5C%5C%5C%5Ctan%20%5C%2025%20%3D%5Cfrac%7Bx%7D%7B11%7D%5C%5C%5C%5C0.4663%20%3D%5Cfrac%7Bx%7D%7B11%7D)
0.4663 * 11 = x
x = 5.1293
x = 5.1
Based on the calculation, the perimeter of the horizontal cross-section is equal to 36.13 cm.
<h3>How to calculate the perimeter?</h3>
In this scenario, the resulting geometrical shape formed when the cut is made at the middle of the height of the trapezoid and then rotated is a circle.
<u>Given the following data:</u>
From the middle, the diameter of this circle is given by:
D = 1/2 (10 + 13)
D = 11.5 cm.
Now, we can calculate the perimeter:
Perimeter = πD
Perimeter = 3.142 × 11.5
Perimeter = 36.13 cm.

Answer:
Segment AC = 10 units
segment AD =
angle 1 = 45°
angle 2 = 90°
AE = BE = CE = DE = 5
SEGMENT AC = AE + CE
= 5 + 5
= 10 UNITS
SEGMENT AD = 5² + 5²
= √50
= 7.071
= 7 UNITS
ANGLE 1 = 90° ÷ 2
= 45°
ANGLE 2 = 360° ÷ 4 / 180° ÷ 2
= 90°
