A

Step-by-step explanation:

30 minutes = half an hour

Carly:

450/2 = 225

620/2= 310

225 + 310 = 535

Carly burned 535 calories total

Sarah:

560/2 = 280

510/2 = 225

280 + 225 = 505

Sarah burned 505 calories total

Carly burned more calories than Sarah

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.
