This looks like a deformed pentagon anyways angle sum of pentagon 540
so u just to minus everything off 540
540-121-100-108-102
=109
Answer: there are a total of 7 marbles
Step-by-step explanation:
The chance of the first marble being blue is 4/7. Now we only have 6 marbles in the bag (3 red and 3 blue)
The chance of the second marble being blue is 3/6
The LCD here is 12. Th,us, 1/6, 2/3 and 1/4 become:
2/12, 8/12 and 3/12.
Their sum is 13/12, or 1 1/12.
150/4.25
=35.29
So that would need to be rounded and you would get about 35!
