Answer:

460 mi²

Step-by-step explanation:

The surface area consists of 3 rectangles of the sides, and the two base triangles.

The front rectangle has dimensions of 10x11, so it's area is 110 in²

The left side rectangle has dimensions of 10x11, so it's area is 110 in²

The right side rectangle has dimensions of 12x11, so it's area is 132 in²

The top and bottom triangles have a base of 12 and a height of 8, so their area is

A = (1/2)(12)(8) = 108/2, but there are 2 of them, so their combined area is (108/2)(2) = 108 in²

The total surface area is 110 + 110 + 132 + 108 = 460 mi²

Verify that the following equation is an identity. (1/sinx) - (1/cscx) = cscx - sinx

Anarel [89]

Manipulating the left side of the equation, we obtain:

$\dfrac{1}{\sin x}-\dfrac{1}{\csc x}=\dfrac{\csc x-\sin x}{\sin x\cdot\csc x}$

Using that $\csc x=\dfrac{1}{\sin x}$ :

$\dfrac{\csc x-\sin x}{\sin x\cdot\csc x}=\dfrac{\csc x-\sin x}{\sin x\cdot\dfrac{1}{\sin x}}=\dfrac{\csc x-\sin x}{1}=\csc x-\sin x\\\\\boxed{\dfrac{1}{\sin x}-\dfrac{1}{\csc x}=\csc x-\sin x}~~\blacksquare$
