Asked by gabriel

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.
Answered by helper
x = 1st angle
90 - x = 2nd angle
5x - 16 = 3rd angle

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