Question

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg?

A. 51 feet

B. 61 feet

C. 78 feet

D. 80 feet

Answer 1

The Pythagorean Theorum formula is a^2+b^2=c^2.

The hypotenuse equals c. Let's say that the 35-foot leg is b. That makes our formula c^2-b^2=a^2.

C Squared=4,900

B Squared=1,225

C Squared-B Squared=3,675

If we square root 3,675, that gives us our final answer, 60.6. Let's round it to 61.

The answer would now be B.
