Answer:
The answer is cscx(cscx - 1) ⇒ the second answer
Step-by-step explanation:
∵ csc²x = cot²x + 1
∴ 
Multiply the fraction by its conjugate 1 - sinx (up and down)
∴ 
∵ 1 - sin²x = cox²x
∴ 
∵ cot²x = cos²x/sin²x
∴ 
Take cscx as a common factor
∴ cscx(cscx - 1)

Use the formula for the volume of a triangular pyramid: V=13Ah , where A = area of the triangular base, and H = height of the pyramid.
Answer:
If the diameter or radius of one circle is the same as another circle they are congruent.
Answer: the exact perimeter of the figure is 53.68 cm
Step-by-step explanation:
The angle formed by the shaded sector is
360 - 90 = 270 degrees
We would determine the length of the arc formed by the shaded portion by applying the formula for length of arc which is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Radius, r = 8 cm
θ = 270 degrees
Length of arc = 270/360 × 2 × 3.14 × 8
= 37.68 cm
Perimeter of the figure is
Length of arc + radius + radius
It becomes
37.68 + 8 + 8 = 53.68 cm
