Question

I need help on more Pythagorean Theorem word problems, please.

Answer 1

to solve 47, you would add.

a² (33) + b²(44) = c²

33² = 1,089
44²= 1,936.

1,089 + 1,926= 3,024.

√3,024= 54.9

to solve 48, you would subtract.

9² - 5.4² =x²

9² = 81.
5.4²= 291,16.

81 - 29.16= 51.84.

√51.84=7.2
7.2 = x

hopefully this helps
