The length of the other leg to the nearest tenth of a foot is 5.7 feet.
What is Pythagorean theorem?
A theorem in geometry: the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
The Pythagoras theorem equation is expressed as, , where 'c' = hypotenuse of the right triangle and 'a' and 'b' are the other two legs.
We can use the Pythagorean Theorem to find the length of the other leg
"a" and "c" represent the two legs of the triangle and "b" represents the perpendicular.
So,
= 7² - 4²
b =
⇒ 5.7 feet
Therefore, the length of the other leg to the nearest tenth of a foot is 5.7 feet.
