What is the value of x?

Since the line bisects the right angle of the larger triangle, the angle opposite 3 in the triangle on top is 45 degrees (90/2 = 45).

sin 45 = 3/x

=

x = 3

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
