For the following diagram, assume that l || m. solve for each of the variables, w, x, y, and z. for each solution, explain, in complete sentences which special angles allowed you to create an equation in order to find a solution.

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
