The shorter leg of the right triangle is 8 less than the hypotenuse. The longer leg is 1 less than the hypotenuse. Find the peri
Wewaii [24]
Hypotenuse = h
leg1 = h-8
leg2 = h-1

h² -(h-8)² = (h-1)²

h² - [h² -16h +64] = h² -2h +1
16h -64 = h² -2h +1
h² -18h + 65 = 0

hypotenuse = 13
leg1 = 13-8 = 5
leg2 = 13-1 =12

Perimeter = 13 + 5 + 12 = 30

Joe's workout at the gym was a total of 90 minutes. If he spent 1/3 of the time lifting weights, how much time did he have left
atroni [7]

Answer:

60 minutes, or 1 hour.

Step-by-step explanation:

90 minutes ÷ 3 = 30 minutes, so 30 minutes equals 1 third of the total time he spent at the gym, and he lifted weights for 30 minutes. The remaining 2 thirds, 60 minutes, is the time he spent on the treadmill.
