Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18
So the first angle is 18° and the second is 72° (18*4)
Hope this helps
If the line has a slope of 4, then a line perpendicular to it would have a slope of -1/4.
If the line has a slope of -4, then a line perpendicular to it would have a slope of 1/4.
The relation of slopes between two perpendicular lines is m1*m2=-1
