Find the length of the hypotenuse of a right triangle whose legs are 8 and 15 units in length.

Question

kropot72 · Answer

Do you know the theorem of Pythagoras?

kropot72 · Answer

In any right-angled triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides. So in your question, if we let h be the hypotenuse, we get:
$$h ^{2}=8^{2}+15^{2}$$
Do you know how to find h?

okay well what about this one? Which of the following is the equation of a circle whose center is at the origin and whose radius is 4?

kropot72 · Answer

The equation of a circle whose center is at the origin and whose radius is R is:
$$x ^{2}+y ^{2}=R ^{2}$$
Now you should be able to choose the correct answer.
