Drew is making a cardboard cut out of a right triangle. He knows that the longest side must be 15 inches long. One of the short sides must be 8 inches. How many inches long will he make the other side? Use the appropriate formula to find the solution and round to the nearest tenth. Show all steps or reasoning used. Be sure to check your answer for reasonableness

Question

lgbasallote · Answer

right triangle so use pythagorean formula...longest side means hypotenuse so

$$a^2 + (8^2) = 15^2$$

lgbasallote · Answer

therefore $$a^2 = 15^2 - 8^2$$ to get a just take the square root $$a = \sqrt{15^2 - 8^2}$$ got ti??
