8. What is the area of the triangle above?
a = x, b = 2x, and c = 3x.
The side opposite a is 4 and the side opposite b is 3.
From we can determine the measures of the angles: a + b + c = x + 2x + 3
x = 6x = 180
Dividing the last equation by 6 gives: x = 30
Hence, a = 30, b = 60, and c = 90. However, different size triangles can have these angle measures, as the diagram below illus
