Answer:
b = -2
Step-by-step explanation:
1) Cross multiply the proportion, in turn, you receive 2(b-4) = 6b.
2) Simply said equation, you should have 2b - 8 = 6b.
3) Subtract the 2b from each side, effectively canceling it out on the left (original position) and resulting in 6b to become 4b (6b - 2b = 4b).
4) After you have -8 = 4b, you can divide both sides by 4, canceling out on the right (original position).
5) You are finally left with -2 = b, reversing this results in b = -2. 
-2 is your answer.
 
        
             
        
        
        
Sin(x)=cos(90-x); therefore x=68º
        
             
        
        
        
X=15 its simple since there's base angles and straight angle
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
5. a) ∠1 and ∠2 are remote interior angles of ∠ACD so that means that ∠ACD = ∠1 + ∠2
    b) Because an exterior angle is the sum of its two remote interior angles it makes sense that an exterior angle is greater in measure than either of its remote interior angles.
6. BD = DB  Reflexive property
     ∠3 = ∠5, ∠4 = ∠6  Alt. int. angles
     ΔADB = ΔCDB   ASA
7. AB = BC Def. of midpoint
    ∠1 = ∠2 Given
    ∠BAE = ∠CBD Corresponding angles
    ΔBAE = ΔCBD ASA
     ∠D = ∠E CPCTC
