First, I will add up the know amount of points Chef Curry scored
45 + 48 + 32 + 40 = 165
To find the mean, add up all the numbers and divide that by how many values you had
I know 210 / 5 = 42, so I will subtract:
210 - 165 = 45
Cheer Curry scored 45 points

Answer:
I believe it is C. division
The small right angled triangle with hypotenuse vale 5 is similar to the big triangle with b as the hypotenuse
Corresponding sides are in the same ratio so we can write
a/12 = 5/b.....(1)
Also applying pythagoras theorem to the large triangle
b^2 = 5^2 + 12^2
b^2 = 169
b = 13
So substituting in equation (1):-
a / 12 = 5 / 13
a = (5*12 ) / 13
