The side lengths of different triangles are given. Which triangle is a right triangle?

Without having any of the side lengths, we would only be able to identify a right angle if there is a small square in the corner of any of the angles. That would indicate a right angle and there for a right triangle.

With the side lengths, you can go by the pythagorean theorem or if side A and side B equal side C or the hypotenuse (the longest side, which is alway directly across from the right angle.)

A + B = C it would be a right angle.

Step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
