Find the area of the triangle. round your answer to the nearest tenth.
a. 742.9 yd2
b. 1,458 yd2
c. 1,323.8 yd2
d. 661.9 yd2

Use A = (ab•sin C)/2.

A = (54•54)•sin(27)/2

A = 661.9181486203

We now round off to the nearest tenths, which means to 1 decimal place.

A = 661.9 yards^2

Choice D

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.
