Question

If a square with a width of 30 feet a length of 72 feet, and the diagonal is 78 feet, would the square have right angles. Yes or No answer please explain

Answer 1

Yes. Use the Pythagorean theorem. 30 would be a. 72 would be B. 78 would be C.
Formula:
A^2 + B^2= C^2
A squared Plus B squared equals C squared

30 squared is 900
72 squared is 5184
900+5184 = 6084

78 squared is 6084

Therefore the triangle has a right angle.
