Answer:
YES
Step-by-step explanation:
To see if it is a right triangle, find the relationship using:
[tex]a^2+b^2[/tex]_[tex]c^2[/tex]
If the sum of a and b squared is equal to c (the Pythagorean theorem) then it is a right triangle.
Insert the values, with the biggest number being c (this is because c represents the hypotenuse, and the hypotenuse is the longest side of a triangle):
[tex]15^2+36^2[/tex]_[tex]39^2[/tex]
Simplify exponents:
[tex]225+1296[/tex]_[tex]1521[/tex]
Simplify addition:
[tex]1521[/tex]_[tex]1521[/tex]
Find the relationship:
[tex]1521=1521[/tex]
It is a right triangle.
Finito.
