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. The formula for solving the area of a right triangle is 1/2 b * h.
The base is 6, and the height is 8.
That means that the 1/2 b * h = 3 * 8.
Since 3*8 = 24, the area of the triangle is 24 square units.
2. The sum of all the angles in a triangle is 180.
180 - 135 - 30 = 15 degrees.
