Answer 1

Answer:

YES

Step-by-step explanation:

To see if it is a right triangle, find the relationship using:

$a^2+b^2$_$c^2$

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):

$15^2+36^2$_$39^2$

Simplify exponents:

$225+1296$_$1521$

Simplify addition:

$1521$_$1521$

Find the relationship:

$1521=1521$

It is a right triangle.

Finito.
