Question

A triangle has two sides that measure 4ft and 3ft. Which could be the measure of the third side?

Answer 1

Use this equation: a^2+b^2=c^2. input the two numbers into the first two variables

Answer 2

The measure of the third side must be less than the sum of the other two. That property is valid for all triangles.

For this question, call x the measure of the third side. So you must have

x < 4 + 3

x < 7 ft

The only option that satisfies the condition above is

option A) 5 ft.

I hope this helps. =)
