Answer:
a) 5m b) 53°
Step-by-step explanation:
a) √Bc²+AB²
=√4²+3²
=√16+9 
=√25 =5m
b) tan θ =BC/AB
tanθ =4/3
so tan θ=53°
 
        
             
        
        
        
The angles get added.
Let <em>z</em> = <em>r</em> exp(<em>i</em> <em>θ</em>) and <em>w</em> = <em>s</em> exp(<em>i</em> <em>φ</em>). Then
<em>zw</em> = <em>rs</em> exp(<em>i</em> <em>θ</em>) exp(<em>i</em> <em>φ</em>) = <em>rs</em> exp(<em>i</em> (<em>θ</em> + <em>φ</em>))
 
        
             
        
        
        
No, It's not. 
coefficients for perfect square would be: 
3² - 2(3)(6) + 6² = 9 - 36 + 36
