Which of the following could be the side measures of a right triangle?
A. 6 ft, 5 ft, 4 ft
B. 8 ft, 7 ft, 6 ft
C. 10 ft, 8 ft, 6 ft
D. 12 ft, 10 ft, 8 ft

C

Step-by-step explanation:

First, let us try the first on:

sqrt (5^2+4^2)=sqrt 41 so it can't be A

Second one:

sqrt (6^2+7^2)=sqrt 85, no

Third one:

sqrt (8^2+6^2)=sqrt 100 = 10, so it is C

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
