Angles can be used to estimate the side lengths of a shape.
The letters in order of greatest to least are (a), (b) and (c)
The sum of angles at side (a) is:
![a = 30 + 50](https://tex.z-dn.net/?f=a%20%3D%2030%20%2B%2050)
![a = 80](https://tex.z-dn.net/?f=a%20%3D%2080)
The sum of angles at side (c) is:
![c = 50 + 90](https://tex.z-dn.net/?f=c%20%3D%2050%20%2B%2090)
![c = 140](https://tex.z-dn.net/?f=c%20%3D%20140)
The sum of angles at side (b) is:
![b = 40 + 90](https://tex.z-dn.net/?f=b%20%3D%2040%20%2B%2090)
![b = 130](https://tex.z-dn.net/?f=b%20%3D%20130)
So, we have:
![a = 80](https://tex.z-dn.net/?f=a%20%3D%2080)
![b = 130](https://tex.z-dn.net/?f=b%20%3D%20130)
![c = 140](https://tex.z-dn.net/?f=c%20%3D%20140)
The smaller the base angles, the longer the side.
Hence, the letters in order of greatest to least are (a), (b) and (c)

<em> </em>
<em>y = x - 2</em>
<em>P(0, -2) and (2,0) on this line: Plot and connect with the Line.</em>
<em>P(-2,-4) is the ordered pair that is the solution for this system of EQs</em>
<em>On may CHECK by substituting x= -2 and y = -4 into the EQs of these Lines</em>

<em>Hope this helps!!!</em>
Step-by-step explanation:
To get the inverse, swap the x- and y-variables, then solve for y. We should have the equation: ![x = 2y^2 - 8](https://tex.z-dn.net/?f=x%20%3D%202y%5E2%20-%208)
Solving for y:
because
or ![x =\sqrt\frac{y + 8}{2}](https://tex.z-dn.net/?f=x%20%3D%5Csqrt%5Cfrac%7By%20%2B%20%208%7D%7B2%7D)
So on interchanging the variable, we get the equation:
D 5/8 i believe
because 5 up and 8 down seems right
