You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.
But, 3.5^2 + 4.5^2 is not equal to 5.5^2.

Answer:
3*57=171
Step-by-step explanation:
We want the probability of at least 1 girl. Lets look at the probability of the opposite: all boys. There is a 1/2 chance at each birth that the child will be a boy, so for that to happen 3 times in a row, the odds are 1/2 * 1/2 * 1/2 = 1/8.
Any other possible composition of the family meets the condition laid down, so the odds of at least 1 girl are 1-1/8 = 7/8.
