Evaluate<span> the series by expanding the summation, then adding all of the values. 154 would be the answer.</span>
Solution:
we are given that
In a class, every student knows French or German (or both).
15 students know French, and 17 students know German.
Suppose there are x student who knows both French and German.
Then Total number of student in the class will be 
But to guess the largest possible number of student in the class we can assume x=0
Hence the largest Possible number of Student in the class=32
I believe the correct answer is: B. But I’m not sure.
Step-by-step explanation:
y for the last one i dunno about the other 2 cause i cant see there drop down menus
Let the third angle = x
It would be: 35 + 45 + x = 180
80 + x = 180
x = 180 - 80
x = 100
So, your final answer is 100
Hope this helps!
