Step-by-step explanation:
do the math and u get ur answer
Step-by-step explanation:
the two opposites Angles of this quadrilateral are equal, again the angles should sum up to 360
t-9+t-91+t-16+t+25=360
4t=360-101
4t=259
t=64.75
Answer:
Your expression equals
assuming the problem was to simplify
to the form
.
Step-by-step explanation:
![2\sin(\frac{\pi}{8}) 2\cos(\frac{\pi}{8})](https://tex.z-dn.net/?f=2%5Csin%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29%202%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29)
![2(2)\sin(\frac{\pi}{8})\cos(\frac{\pi}{8})](https://tex.z-dn.net/?f=2%282%29%5Csin%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B8%7D%29)
Let's use the following identity: ![2\sin(A)\cos(A)=\sin(2A)](https://tex.z-dn.net/?f=2%5Csin%28A%29%5Ccos%28A%29%3D%5Csin%282A%29)
![2\sin(2 \cdot \frac{\pi}{8})](https://tex.z-dn.net/?f=2%5Csin%282%20%5Ccdot%20%5Cfrac%7B%5Cpi%7D%7B8%7D%29)
which is comparable to the form
.
![a=2](https://tex.z-dn.net/?f=a%3D2)
![\theta=\frac{\pi}{4}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B%5Cpi%7D%7B4%7D)
Answer:
Perimeter = 22.809836694575
Step-by-step explanation:
A(-2, 2) ; B(6,2) ; C(0, 8)
![AB=\sqrt{\left( 6--2\right)^{2} +\left(2-2 \right)^{2} } =\sqrt{64} =8](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%5Cleft%28%206--2%5Cright%29%5E%7B2%7D%20%20%2B%5Cleft%282-2%20%5Cright%29%5E%7B2%7D%20%20%7D%20%3D%5Csqrt%7B64%7D%20%3D8)
![AC=\sqrt{\left( 0--2\right)^{2} +\left(8-2 \right)^{2} } =\sqrt{40} =2\sqrt{10}](https://tex.z-dn.net/?f=AC%3D%5Csqrt%7B%5Cleft%28%200--2%5Cright%29%5E%7B2%7D%20%20%2B%5Cleft%288-2%20%5Cright%29%5E%7B2%7D%20%20%7D%20%3D%5Csqrt%7B40%7D%20%3D2%5Csqrt%7B10%7D)
![BC=\sqrt{\left( 0-6\right)^{2} +\left(8-2 \right)^{2} } =\sqrt{72} =6\sqrt{2}](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B%5Cleft%28%200-6%5Cright%29%5E%7B2%7D%20%20%2B%5Cleft%288-2%20%5Cright%29%5E%7B2%7D%20%20%7D%20%3D%5Csqrt%7B72%7D%20%3D6%5Csqrt%7B2%7D)
Then
The perimeter of ΔABC = AB + BC + AC
![=8+6\sqrt{2} +2\sqrt{10}](https://tex.z-dn.net/?f=%3D8%2B6%5Csqrt%7B2%7D%20%2B2%5Csqrt%7B10%7D)
= 22.809836694575
