The answer is C because 100 doesn’t change but 12 is dependent on the number of people.
Area of a triangle is equal to 1/2 b(h) so since you already have the height and base, all you need to do is input it back into the equation:

(10)(13)
Multiply 10 & 13 to equal

(130)
Then take half of 130 to get
A = 65
The missing angle would be 68 because the the triangles can be alternate exterior
12% aka 12 days it didn't rain
Answer:
I believe it would be 9 & 10. 9^2 is 81 and 10^2 is 100 which are numbers that fall in between √111.
