Answer:
Use the Pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex] where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:
[tex]3^{2} +4^{2} =c^{2}[/tex]
Simplify the equation to get:
[tex]9+16=c^2[/tex]
Add 16 and 9 to get 25 and take the square root of both sides:
[tex]\sqrt{25} =c[/tex]
The sqrt of 25 is 5. Therefore, the length of the hypotenuse, or c, is 5.
