B. √4222
C. 142
D. 122
E. 2640
F. 98

(Picture below.)

Answer 1

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.

Answer 2

22^2 + 120^2 = c^2

Then take square root of that..

Answer 3

Would it be B, then?

Answer 4

its D
