Answer:
First blank is cos(h)cos(x)
Second blank is sin(x)
Step-by-step explanation:
Look up the identity and apply it here
 
        
             
        
        
        
This involves basic arithmetic calculations and simultaneous equations.
Adamu has 25 Cards
Let the following letters represent the number of cards each has;
A: ADAMU
F: FUNKE
S: SHEHU
K: KWAME
T: TANKO
- If adamu gives funke 5 cards, he will have as many as tanko. Thus;
A - 5 = T  --- eq 1
- If funke gives adamu 4 cards, he will have as many as kwame. Thus;
A + 4 = K  --- eq 2
- Funke and adamu have a total of 13 more cards than the total that kwame and tanko have. Thus;
A + F = K + T + 13   --- eq 3
- Adamu has 2 cards more than what Shehu has. Thus;
A - 2 = S  --- eq 4
From online research, the Total Number of cards is 134 and not 133. Thus;
A + F + K + S + T = 134  --- eq 5
Let's put A - 5 = T and A + 4 = K in eq 3 to get;
A + F = (A + 4) + (A - 5) + 13
A + F = 2A + 12
F = 2A - A + 12
F = A + 12
Let's put A - 2 = S ; F = A + 12 ; A - 5 = T and A + 4 = K into eq 5 to get;
A + A + 12  + A + 4 + A - 2 + A - 5 = 134
Simplifying gives;
5A + 9 = 134
5A = 134 - 9
5A = 125
A = 125/5
A = 25
Adamu has 25 Cards
 
        
             
        
        
        
48 divide by 4 sides = 12
12 x 12 = 144cm squared
        
                    
             
        
        
        
Answer:
the 3rd one x+2=5 
Step-by-step explanation:
Why? 
because you are going from small # to a bigger # so you know you are adding 
there is 2 there and it says that it = 5
