Answer:
6 3/10 or as a decimal 6.3
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)

Answer:
2.98
Step-by-step explanation:
Let's begin by evaluating f(x) using the value of 3: f(x) = 2x2 - 4x - 4 (original function) f(3) = 2(3)2 - 4(3) - 4 (plugging in 3 for x) f(3) = 2 (computed result) Now let's evaluate g(x) using the value of 3: g(x) = 4x - 7 (original function) g(x) = 4(3) - 7 (plugging in 3 for x) g(x) = 5 (computed result) Finally, we'll sum our results: (f + g)(3) = 2 + 3 (add f(3) and g(3)) <span>(f + g)(3) = 5 (final answer)</span>
