Chelsea is making a kite in the shape of a triangle. to determine if the triangle is a right triangle, chelsea completed the following steps. step 1: find the side lengths of the triangle: 30 inches, 24 inches, 18 inches. step 2: substitute the values into the pythagorean theorem: 18^2 +24^2=30^2 step 3: combine like terms: (18+24)^2+30^2 step 4: evaluate each side: 1764≠900 chelsea says the triangle is not a right triangle. which best describes the accuracy of her explanation? a) the triangle is actually a right triangle. in step 2, chelsea incorrectly substituted the values into the pythagorean theorem. b) the triangle is not a right triangle, but in step 2 chelsea incorrectly substituted the values into the pythagorean theorem. c) the triangle is actually a right triangle. in step 3, chelsea incorrectly rewrote the expression on the left side of the equation. d) the triangle is not a right triangle, but in step 3, chelsea incorrectly rewrote the expression on the left side of the equation.
