Hi,
1)An angle's measure is 18° more than 3 times its complement.
Let x represent the angle and (90° - x) represent its complement
Question states******
 x = 3(90°-x) + 18°
Solving for x
 4x = 288°
  x = 72°, the angle, its complement is 18°
CHECKING our Answer*****
  {{{72 = 3*18 + 18}}}
2)The supplement of an angle is 4 times as large as the angle's complement.
Let x represent the angle, (90° - x)its complement & (180°-x) its supplement
Question states***
 (18°0-x) = 4(90°-x)
Solving for x
  3x = 180°
   x = 60° the angle, complement is 30° and supplement is 120°
CHECKING our Answer***
 {{{120 = 4*30}}}
