Triangle Measurements and Pythagorean Theorem

The video tutorial explains how to determine the base and height of a right triangle using the Pythagorean theorem. It starts by identifying the hypotenuse and defining the relationship between the base and height. The tutorial then applies the Pythagorean theorem to set up a quadratic equation, which is solved to find the base's length. Finally, the video demonstrates how to calculate and round the base and height to the nearest hundredth.

What is the hypotenuse of a right triangle?

• The side adjacent to the right angle

• The side forming the right angle

• The shortest side

• The side opposite the right angle

What is the quadratic formula used to solve the equation?

• x = (-b ± √(b^2 + 4ac)) / 2a

• x = (b ± √(b^2 - 4ac)) / 2a

• x = (b ± √(b^2 + 4ac)) / 2a

• x = (-b ± √(b^2 - 4ac)) / 2a

Why is only the positive solution of x considered in this problem?

• Because negative solutions are not allowed in algebra

• Because x is a length and must be positive

• Because the quadratic formula only gives positive solutions

• Because the problem specifies only positive numbers
