18 lines of symmetry the dome have, after excluding the spire of the dome.
36 ÷ 2 = 18
3 row × 36 windows per row, total windows = 108. 36 of them connects a window with the window across to form 1 line of symmetry.
<h3>What is a symmetry?</h3>
If two additional identical parts that are arranged in an orderly fashion can be divided from a shape, it is said to be symmetrical. As an illustration, if you are instructed to cut out a "heart" from a piece of paper, you need just fold the paper, draw one-half of the heart at the fold, and then cut it out to discover that the second half exactly matches the first half.
Asymmetrical and symmetrical balances are the two types of balance. The two parts of the thing are precisely identical and balanced in symmetrical balance. The two parts of an asymmetrical balance are not similar; rather, separate things are arranged such that they appear to be balanced.

The answer is 6 because you can divid 24 by 4 since the 25% is a quarter of 100%
<u><em>Answer:</em></u>
θ = 76°
<u><em>Explanation:</em></u>
<u>The given equation is:</u>
8 cotθ + 3 = 5
8 cotθ = 5-3
8 cotθ = 2
cot θ = 
<u>Now, we find θ</u>
We know that the cot function is the inverse of the tan function.
The tan of an angle is positive in the first and third quadrants, therefore, the cot will be <u>positive</u> in the <u>first and third quadrants</u> as well
<u>Now, we are given the condition:</u>
0° ≤ x ≤ 90°
<u>Therefore, we know for sure that our angle is in the first quadrant</u>
θ = cot⁻¹(
) = 75.96° = 76° to the nearest degree
Hope this helps :)
