Question

Use the Pythagorean Theorem to determine if the three numbers could be the measures of the sides of a right triangle. Assume that the third measure is the hypotenuse. 3, 7, the square root of 50

A. yes
B. no

Answer 1

a^2 + b^2 = c^2

or

3^2 + 7^2 = sqrt(50)^2

Answer 2

3^2 + 7^2 = 9 + 49 = 58

sqrt(58) does not equal to square root of 50

so it's no

Answer 3

which means

9 +49 = 50

which is not true. The answer is no.
