C(3)=Ishann's age
Ishann is 14 years older than Christopher
7*3=21-7=14
So Christopher is 7 years old
let <ACB=<C,
Here h=26 due to opposite to right angle is hypotenuse and b=10 Is a base and p=24 due to opposite to the angle <C
so,
Cos<C=b/h
=10/26
=5/13
any other details you could give me ?
We have 3 children, with each one possibly being a boy or a girl. And so for each child, the probability of being a boy is 1/2 same with a girl so
1/2^3 = 1/8
so it's 1/8 chance of it being a boy.
