The answer would be OC, most triangles, like right triangles have equivalent sides. 12, 12, 12in
Answer:
is the a. Perpendicular lines form 90° angles.
It's actually easier than it seems. if the tax is paid in equal payments every month and the total throughout a year (12 months) is $2,820, you have to find out how much they pay every month
so divide the total by the number of months
2,820/12=235
they pay $235 in taxes every month
to find out the total of the taxes and the house payment, just add the monthly tax and the monthly house payment.
235+752
and your answer is the sum
You can factor -80 as
![-80 = (-1)\cdot 16 \cdot 5](https://tex.z-dn.net/?f=-80%20%3D%20%28-1%29%5Ccdot%2016%20%5Ccdot%205)
So, we have
![\sqrt{-80} = \sqrt{(-1)\cdot 16 \cdot 5}](https://tex.z-dn.net/?f=%5Csqrt%7B-80%7D%20%3D%20%5Csqrt%7B%28-1%29%5Ccdot%2016%20%5Ccdot%205%7D)
The square root of a product is the product of the square roots:
![\sqrt{-80} = \sqrt{(-1)}\sqrt{16}\sqrt{5}](https://tex.z-dn.net/?f=%5Csqrt%7B-80%7D%20%3D%20%5Csqrt%7B%28-1%29%7D%5Csqrt%7B16%7D%5Csqrt%7B5%7D)
Since
and
, we have
![\sqrt{-80} = 4i\sqrt{5}](https://tex.z-dn.net/?f=%5Csqrt%7B-80%7D%20%3D%204i%5Csqrt%7B5%7D)
