Question

Two sides of a triangle measure 5 in. and 12 in. Which could be the length of the third side?

3 in.
6 in.
10 in.
18 in.

Answer 1

the answer is 10 in

Explanation:

If your trying to find the hypotenuse, which is the diagonal side that connects the angle

You would use Pythagorean theorem:

5x5+12x12=c

5x5=25

12x12=144

Now, 25+144=169

Now find the square root of 169 which is 13 which isn't an answer choice, which means your prolly after a leg.

I assume 12 is the hypotenuse

A(squared)+5x5=12x12

A+25=144

144-25=119

Square root of 119=10.9

So I'm going to go with answer 10 in

Hope that helps!

Answer 2

10 in

Explanation:

12 - 5 < third side < 12 + 5

7 < third side < 17
