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.

Question

campbell_st · Answer

this pythagoras' theorem

call the other short side a

then $$a^2 = 15^2 - 8^2$$

once you have that answer... take the square root... to get the necessary measurement.

anonymous · Answer

so solve a^2=15^2-8^2?
