Question

Find the missing side of the right

triangle if one leg is 6 ft and the
hypotenuse is 8 ft.
A. 28 ft
B. √2 ft
C. 10 ft
D. 2√7 ft
E. 2 ft

Answer 1

Answer D.
Using Pythagorean theorem
a^2 + b^2 = c^2
C^2 (8) is the long diagonal, it is the hypotenuse and (6) is one leg.
6^2 + b^2 = 8^2
rearrange to isolate the unknown
b^2 = 8^2 - 6^2
B^2 = 28
Take square root of both sides
b= 5.3, same as (2 sq.rt. 7) answer D

Answer 2

it's D
