One leg of the triangle is 14 feet longer than the other leg. (pf) 4. Since all triangles have 3 sides and 3 internal angles, it is impossible for a right triangle to have another angle that is greater than or equal to 90, because the third angle would have to be 0 or have a negative angle measurement. The 2+ 2 = 2 The formula is . Transcribed image text: If the hypotenuse of a right b The hypotenuse of the triangle is 19 cm long. The variable "c" will always be assigned to the hypotenuse, or longest side. Choose one of the other sides to be a, and call the other side b (it doesn't matter which is which; the math will turn out the same). Then copy the lengths of a and b into the formula, according to the following example: Last Updated: February 10, 2023 hot dogs were 5$ and hamburgers 6$.if she bought a total of 6 items, how many of each kind did ahe buy?
