) Which of these is NOT equivalent to (2)(cos)(x) (csc)(x)=1
? Showing steps not required
since you will explain in part ii.
A. 2cotθ = 1
B. tanθ = 2
C. 2cos θ = sinθ
D. 2sinθ = cscθ

Alright, lets get started.

Two sides of the rectange are 14 and s.

So, the area of the rectange would be =

So, the area of the rectange would be =

A triangle is cut from the rectangle.

The height of the triangle is =

The base of the triangle is = 14

So area of the triangle would be =

area of the triangle would be =

area of the triangle would be =

So, the area of shaded region = area of rectange - area of triangle

the area of shaded region =

As per given in question, area of shaded region is 84, hence

equation

So, this is the equation for s : Answer

Hope it will help :)
