A triangle has sides with lengths of 11 feet, 15 feet, and 17 feet. Is it a right triangle?

First to find out if this is a right triangle you will setup the equation with a+b=c

11^2+15^2?17^2

first do exponents (11 x 11, 15 x 15, and 17 x 17)

121+225?289

Now add 121 and 225

346?289

now decide whether 346 is equal to 289?

No they are not equal meaning the triangle is not equal.

NO it is not a right triangle

No bc if it was a right angle two of the sides would have to be equal to make the 90 degree side
