The angle bisectors of PQR are PZ, QZ, and RZ. They meet at a single point Z. (In other words, Z is the incenter of PQR.) Suppose YZ = 15, QZ = 20, m< WPY = 94, and m< XQZ = 26. Find the following measures. Note that the figure is not drawn to scale.

Which is a reasonable estimate of the amount of water in a small, inflatable pool used by children?

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
