Atriangle can be formed with side lengths 3 in, 5 in, and 9 in. a) true b) false

According to triangle inequality theorem , sum of two sides must be greater then third side.

But here 3+5=8 which is less then 9. So it is violating triangle inequality theorem. So with the given three measurements, a triangle is not possible.

Therefore the statement is false .

A)
