What is the side of a right triangle across from the right angle called?

• square

• arm

• leg

• hypotenuse

what is the formula for finding the hypotnuse?

• a²⁺b²=c²

• a+b=c

• a-b=c

• c-a=c

What is the length of x?

• 5

• 7

• 8

• 25

Answer explanation

Remember we need to use the Pythagorean theorem, 3 and 4 are our leg lengths. 3 squared plus 4 squared gives us 25. The square root of 25 is 5, so our hypotenuse length is 5.

Use Pythagorean Theorem to solve for x.
