<span>you can factor the left side of the equation to
(csc^2 + cot^2)(csc^2 - cot^2)
then, since cot^2 + 1 = csc^2, you can replace the csc^2 in the left parentheses with cot^2 + 1, and the cot^2 in the right parentheses with csc^2 - 1 (which equals cot^2)
then, youll end up with
(cot^2 + 1 - cot^2)(csc^2 + csc^2 - 1)
combine like terms, and the left parentheses becomes 1 (cot^2 - cot^2 = 0), and the right parentheses becomes 2csc^2 - 1.
1(2csc^2 - 1) = 2csc^2 - 1</span><span>

Answer:
4.5 cm.
Step-by-step explanation:
The volume of the pyramid = 1/3 * area of the base * height.
Area of the triangle = 1/2 * base * height
= 1/2 * 14 * 8
= 56 cm^2.
So the volume of the pyramid =
84 = 1/3 * 56 * h
h = 84 / (1/3 * 56)
h = 84 * 3 / 56
= 4.5 cm.

Answer:
BD is a perpendicular bisector of AC
10^2 + 5^2 = Diagonal length. so, 100 + 25 = 125 diagonal length
