Elijah's Scribe post for January 4 2009

Question #6.

Determine the length for each right angle.

c2 - a2 = b2
25squared - 7 squared = b2
(25x25) - (7x7) = b2
625 - 49 = 576
576 = b2
√ 576 = √ b2
24 = b



t2 - s2 = r2
26squared - 24squared = r2
(26x26) - (24x24) = r2
676 - 576 = r2
100 = r2
√100 = √r2
10 = r2
