they are 27, 28, and 29.
Step-by-step explanation:
Answer:
a rightangle triangle
Step-by-step explanation:
because 72+18=90 degrees
when a side is 90 degrees in a triangle, it is right-angled.
hope this helps you!!
The product would expand to
This is a trinomial, and the only way to make it a binomial is to cancel out a coefficient using our variable 
.
So, we can cancel either the linear term or the constant term.
In the first case, we require
In the second case, we require
But must be a non-zero rational number, so this solution is not feasible.
5) Obtuse triangle because the top angle is more than 90 degrees
Answer:
Yes.
Step-by-step explanation:
Yes, it is possible. For example, 0.2 and 0.2 both have one decimal place and one significant digit. Their product, 0.04, has one significant digit, but has 2 decimal places.
