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
