Answer:
b. complementary 
Step-by-step explanation:
-Complementary angles are angles that add up to 90°.
-These are usually the two acute angles in the right triangle.
#To verify, lets take the two angles 30° and 60°:

#We can reverse as:

Hence, two angles are said to be complimentary if they sum up to 90°.

Answer:
 substitute x= -3
f (-3)=9+24
 =33
 
        
                    
             
        
        
        
JK = JH + HK
JK = 82
JH = 22
So, HK = 82 - 22 = 60, or choice (C).
