Q:

Which are the side lengths of a right triangle? Check all that apply.3, 14, and sqrt2056, 11, and sqrt15819, 180, and sqrt1813, 19, and sqrt3802,9, and sqrt85

Accepted Solution

A:
Answer:3, 14, and sqrt205.2,9, and sqrt85.Step-by-step explanation:Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:3^2 = 9 , 14^2 = 196.9 + 196  = 205  which is the square of sqrt205.So this is a right angled triangle.6^2 + 11^2 = 36 + 121= 157 Not right-angled. 19^2 + 180^2  = 32761  Not right-angled. 3^2 + 19^2 = 370    Not right-angled.2^2 + 9^2 = 85, So this is right angled..
