Answer:

Look below

Step-by-step explanation:

(a) The area of a triangle is:

$A=\frac{1}{2}bh$

The height of this triangle is h and it's base is 4+h so...

$A=\frac{1}{2}*[h*(h+4)]$

$A=\frac{1}{2}*(h^2+4h)\\A=\frac{h^2}{2}+2h$

(b) If the height is 8 cm, then the base is 4+8 which is 12 cm so...

$A=\frac{1}{2}*8*12=4*12=48 \ cm^2$

HELP FAST PLEASE!!!!!

Alright, lets get started.

The answer Sandra got is correct that is zero but there are some mistakes she made while writing steps.

$2 cot(\frac{-9\pi}{2}) = 2 cot(\frac{9\pi}{2})$ Incorrect step

Because as per even/odd identity,

Cot (-Θ) = - cot (Θ)

Hence

$2 cot (\frac{-9\pi}{2}) = - 2 cot (\frac{9\pi}{2})$

Now,

It could be written as

$-2 cot (\frac{9\pi}{2}) = -2 cot (\frac{\pi}{2})$

$-2 * 0$

Hence the answer is 0. : Answer

Hope it will help :)
