1. Find the area of triangle ABC if AB = 6, BC = 8, and angle ABC = 90 degrees.
2. If angle ABC = 135 degrees, and angle ACB = 30 degrees, what is angle BAC?
1. This means that the triangle is right and AB and BC are perpendicular, so use the formula 1/2 * b * h to get 1/2 * 6 * 8 = 3 * 8 = 24
2. The three angles of a triangle add up to 180, if we add 135 and 30 we get 165, and if we subtract that from 180 we get an answer of 15 degrees.
