I think the answer would be c
Answer:
it's probably 8.1
Step-by-step explanation:
:)
P.S: You could use a calculotor next time
1. The angles DCA and BCA are the same.
2. Angles DCA and BCA are not supplementary. Since the both of them add up to 90° (we know that angle c is equal to 90° because in a right square all angles are 90°) the angles would be complementary, not supplementary. Supplementary angles add up to 180°
Answer: Hence, the correct size of boys group is 5 and girls is 6.
Step-by-step explanation:
Since we have given that
Number of boys = 60
Number of girls = 72
We need to divide the students into gender specific groups of the largest possible size.
For this we will find "HCF of 60 and 72" which is equal to "12".
So, the correct size of each group is 12 in which number of boys would be 
Number of girls would be 
Hence, the correct size of boys group is 5 and girls is 6.
