Question

A triangular bookshelf has a base of 10 inches, 12 inches, and 18 inches. Will the bookshelf fit in the corner of a square living room?

Answer 1

Not possible

Explanation:

Since the triangular base has not a right-angled form. That is, the longest side is greater than value of hypotenuse, meaning that triangular base has a form of a obtuse-angle triangle.

1. 10² + 12² = 18² It is not possible because they dont equal
2. 100+ 144= 324
3. 244≠ 324
