Step-by-step guide to solving for side B in a right triangle when given side lengths 73 inches and 55 inches using the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the sum of the squares of the two legs equals the square of the hypotenuse:
a² + b² = c²
Here, suppose you know two sides are 73 inches and 55 inches. To solve for side B, you first need to determine which sides these correspond to: are 73 inches and 55 inches the legs (a and b), or is one of them the hypotenuse (c)?
If 73 inches and 55 inches are the two legs, then the hypotenuse c is:
c = √(73² + 55²) = √(5329 + 3025) = √(8354) ≈ 91.42 inches
If you are solving for B and B is the hypotenuse, then B ≈ 91.42 inches.
Suppose 73 inches is the hypotenuse c, and 55 inches is one leg a, then solve for leg B = b as:
B = √(c² - a²) = √(73² - 55²) = √(5329 - 3025) = √(2304) = 48 inches
Therefore, B would be 48 inches.
Make sure you know which sides you are given to correctly solve for B using the Pythagorean theorem.
