Could somebody help me on this please?

1- longest side

2- adjacent and opposite

3-a^2 + b^2 = c^2

4- yes, by using pythagorean theorem

Step-by-step explanation:

1- the hypotenuse is always the longest side

2- the three sides are called hypotenuse, adjacent and opposite

3- a^2 + b^2 = c^2 is a formula to solve for missing legs

4- pythagorean theorem (a^2 + b^2 = c^2) is the formula to solve for missing legs/hypotenuse . A and B represents a leg and c will always be the hypotenuse, you then isolate for the letter you are missing
