The answer is one eighth because since a whole is 8 and seven eights is eaten, there is one eighth left.
Answer:
D
Step-by-step explanation:
add everything up devide by 3
The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.
60 + 40 + ? = 180
100 + ? = 180
? = 80
The missing angle in the triangle is 80 degrees.

To solve this you must use Pythagorean theorem:
![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = 5
b = 8
c = x
^^^Plug these numbers into the theorem
simplify
25 + 64 = ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
89 = ![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
To remove the square from x take the square root of both sides to get you...
√89 = x
(choice A)
