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.        A_triangle  =  one half the base times the height     

                     A  = (1/2) • 6 • 8  =  24     

 

2.        BAC  =  180 – (135 + 30)     

           BAC  =  15
