Unit pythagorean theorem homework 2 answer key. Mar 27, 2022 · From Geometry, recall that the Pythagorean Theorem is a 2 + b 2 = c 2 where a and b are the legs of a right triangle and c is the hypotenuse. Also, the side opposite the angle is lower case and the angle is upper case. For example, angle A is opposite side a. Figure 1.1. 1. The Pythagorean Theorem is used to solve for the sides of a right triangle.

Answer: Let x cm represent the length of the base of the right triangle. x 2 + 3 2 = 7 2. x 2 + 9 = 49. x 2 = 40. Since 40 is between the perfect squares 36 and 49 but closer to 36, the approximate length of the base is 6 cm. A = 1 2 (6) (3) = 9. So, the approximate area of the triangle is 9 cm 2.Unit 1: Pythagorean theorem Lecture 1.1. A nite rectangular array Aof real numbers is called a matrix.
