Question

The lengths of the legs of a right triangle are 15 cm and 36 cm.



What is the length of the hypotenuse?









A.
21 centimeters







B.
39 centimeters







C.
51 centimeters







D.
57 centimeters

Answer 1

Use your powers of observation. You can eliminate choice A. because the hypotenuse will be the longest side.
You can further eliminate Choices C and D, as those two choices are greater or equal to the sum of the two legs and would not form triangles of any kind let alone a right triangle.

Now you can still work this out without using logic by the Pythagorean theorem.

Answer 2

I suspect you knew the answer already anyway. Good luck with your studies.

Answer 3

I thought it was b @radar am I right

Answer 4

Well if it is not A, C or D, you made the correct choice. good luck in your studies.

Answer 5

Did you decide on B using Pythagorean theorem, or did you eliminate A, C, and D by logic? @ikatouni
