Math Problem Statement

In the right-angled triangle shown, |AB| = 34 and |AC| = 43.36. Find the length |BC| correct to two decimal places.

Solution

In the given problem, we are dealing with a right-angled triangle ABCABC, where:

  • AB=34|AB| = 34 (one of the legs of the triangle),
  • AC=43.36|AC| = 43.36 (the hypotenuse),
  • We are tasked with finding the length of BC|BC|, the other leg, to two decimal places.

Solution:

Using the Pythagorean theorem, we know that in any right-angled triangle:

AC2=AB2+BC2AC^2 = AB^2 + BC^2

We can rearrange this formula to solve for BC|BC|:

BC2=AC2AB2BC^2 = AC^2 - AB^2

Substitute the given values:

BC2=43.362342BC^2 = 43.36^2 - 34^2

Let me calculate this for you.The length of BC|BC| is approximately 26.9126.91, correct to two decimal places.

Would you like further details or clarifications on this solution? Here are five related questions to explore:

  1. How does the Pythagorean theorem work for non-right triangles?
  2. Can the Pythagorean theorem be used in 3D geometry?
  3. What are the applications of right triangles in real-world problems?
  4. How do you determine which side is the hypotenuse in a right triangle?
  5. What other methods can be used to solve triangles besides the Pythagorean theorem?

Tip: Always ensure that your triangle is a right triangle before applying the Pythagorean theorem.
