Let's take this step by step. First, let's find the area of the triangle:
A_t = \frac{1}{2}bh = \frac{1}{2}(13-7)(4+4)= \frac{1}{2}(6)(8) = 24cm^2

Small rectangle:
A = lw = 7*4 = 28cm^2

Big rectangle:
A = lw = 10*4 = 40 cm^2

Let's add all the areas up:
A_T = 24+28+40 = 92cm^2

So, your answer is: The area of this figure is 92 cm².

Find the exact value by using a half-angle identity.<br><br> tan seven pi divided by eight
murzikaleks [220]

Answer:

  1 -√2

Step-by-step explanation:

  \tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}

tan(7π/8) = 1 -√2

I don't know what I am doing help please (C:
NeX [460]

Answer:

Step-by-step explanation:

The far right side of the triangle is 17 cm, which is the height.

The base would be 34 minus 17 because whole length of the rectangle is 34 and the triangle covers all but 17 of it.

So then you would take 1/2 of 17.

Then multiply it by 17 to get 160.5
