QUICK HURRY I NEED THE ANSWER TOO 10(-11) HURRY

Which triangles area would be calculated using the trigonometric area formula

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Show your workcan a right triangle have this sides? *how to prove it without using the pythagorean theorema*
