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°

Answer:
What do you have to do what is the question asking
Step-by-step explanation:
 
        
             
        
        
        
A.) f(x) = x^2 because 2 > 1. So f(2) = 4. 
A is correct. 
B.) f(x) = x^2 because 5 > 1. So f(5) = 25. 
B is incorrect. 
C.) f(x) = 2x because -2 < 1. So f(-2) = -4. 
C is incorrect. 
D.) f(x) = 5 because x = 1. 
D is correct. 
So the answer is A and D.
