Which set of side length form a right triangle?
a) 3ft, 5ft, 6ft
b) 15ft, 39ft, 36ft
c) 7ft, 10ft, 26ft
d) 12ft, 13ft, 14ft

explain when you answer

B. 15ft, 36ft, 39ft

use pythagorean theorem

a²+b²=c²

225+1296=1521

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
