A triangular pyramid has a base shaped like a right triangle. The legs of the right triangle are 15 and 17 centimeters long. The pyramid's height is 9 centimeters. What is its volume?

*segment an is an altitude of right ? abc with a right angle at a. if ab = 2root 5 in and nc = 1 in, find bn, an, ac.

Let u = {q, r, s, t, u, v, w, x, y, z} a = {q, s, u, w, y} b = {q, s, y, z} c = {v, w, x, y, z}. list the elements in the set. a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}

What is the mean of the data set 125, 141, 213, 155, 281
