the first angle of a triangle is complementry to the third angle.
the second angle is 16 degrees less than five times the first angle.

find the measure of the largest angle of the triangle.

• geomitry -

x = 1st angle
90 - x = 2nd angle
5x - 16 = 3rd angle

x + 90 - x + 5x - 16 = 180
solve for x

• geomitry -

x=21.2
