Answer:
 3° and 87°
Step-by-step explanation:
 <em>here's</em><em> your</em><em> </em><em>solution</em>
<em> </em><em>=</em><em>></em><em> </em> we know that measure of complementary angle is 90°
 =>. one angle is.  = x
   => other angle is .= (19x + 30)
 => so, x + 19x + 30° = 90° 
 => 20x + 30° = 90°
 => 20x = 60° 
 => x = 60/20
 => x = 3°
 hence one angle is 3° and other is 87°
