Answer 1

Ok, what's the question?

Answer 2

The hypotenuse of a right triangle is 50 millimeters long. One leg of the right triangle is 30 millimeters long. What is the length of the other leg?

20 millimeters
30 millimeters
40 millimeters
60 millimeters

Answer 3

Again we use pyragothean theorem (a^2 + b^2 = c^2), but this time we set it up as follows:
50^2 = 30^2 + b^2

Answer 4

Then 50^2 - 30^2 = b^2
2500 - 900 = b^2
b^2 = 1600
b = \[\sqrt{1600}\]
b = 40 centimeters
