Given that the length of the hypotenuse of a right triangle is 24, the length of one right triangle is 16, find the length of the other right triangle
Using Pythagorean theorem
Length of the other right angle = √ (24 & # 178; - 16 & # 178;)
=√(576-256)
=√320
=√64×√5
=8√5
Answer: the length of the other right angle is 8 times that of the root sign 5
If the two right sides of a right triangle are 7 and 24 respectively, the length of the middle line on the hypotenuse is______ ．
∵ the two right sides of a right triangle are 7 and 24 respectively ∵ the length of the oblique side of the right triangle is 72 + 242 = 25 ∵ the length of the middle line on the oblique side is 12.5

- 4. The clock indicates 2:15. What is the acute angle between its hour hand and minute hand? The minute hand of the clock goes every minute: 360 / 60 = 6 degrees, Hour hand per minute: 360 / 12 / 60 = 0.5 degrees, So at 2:15, the angle between the hour hand and 12:00 is 0.5 * 15 + 2 * 30 = 67.5 degrees, The angle between the minute hand and 12 o'clock is: 6 * 15 = 90 degrees, Therefore, the acute angle between the hour hand and minute hand is 90-67.5 = 22.5 degrees This is the answer. But I still don't understand! "At 2:15, the angle between the hour hand and 12:00 is 0.5 * 15 + 2 * 30 = 67.5 degrees." Why 0.5 * 15 + 2 * 30,
