What is the length of BC in the right triangle below? A. 14844 B. √4222 C. 142 D. 122 E. 2640 F. 98 (Picture below.)
Use the Pythagorean Theorem... if "a" and "b" are the lengths of the legs of the triangle, then the diagonal "c" is given by: a^2 + b^2 = c^2 So you have "a" and "b" shown in the diagram... square each one, then add them... that will be equal c^2. Then take the square root of that sum... square root of c^2... to get "c", the length of the diagonal.
22^2 + 120^2 = c^2 Then take square root of that..
Would it be B, then?
