Try to solve! The Brook's are installing a wide-screen television with a 60-inch diagonal. Their entertainment center is 48 inches wide by 36 inches high, will the television fit in their current entertainment center?

Special TrianglesThe side lengths of the 45-45-90 triangle and the 30-60-90 triangle share a special relationship.They can be calculated without using a trigonometric ratio.

Anytime three points lie in relation to each other in such a way that a 90-degree relationship is established, Pythagorean Theorem and trigonometric ratios may be used to solve for any missing side or angle measures.
