Answer:
Step-by-step explanation:
tan Θ + tan 2Θ + √3 tan Θ tan 2Θ = √3
tan Θ + tan 2Θ = √3 - √3 tan Θ tan 2Θ
tan Θ + tan 2Θ = √3 ( 1 - tan Θ tan 2Θ)
(tan Θ + tan 2Θ) / (1 - tanΘ tan 2Θ) = √3
tan(Θ  + 2Θ) = √3
tan 3Θ = tan ( )           we know tan Θ = tan α; Θ = nΠ + α, n belongs to z
)           we know tan Θ = tan α; Θ = nΠ + α, n belongs to z
3Θ = nΠ + Π/3
Θ = nπ/3 + Π/9 for all n in Z
 
        
             
        
        
        
Answer:
Option a
Step-by-step explanation:
Lets verify
RHS

- Use distributive law
- a(b-c)=ab-bc



Hence verifed
 
        
                    
             
        
        
        
Answer:
let required no be x

by doing crisscrossed multiplication

42=7x
dividing both side by 7

6=x
therefore x=6
therefore value of remaining no.is 6
 
        
                    
             
        
        
        
%66.666 
Because 4/6 times it will be that which is %66.666
        
             
        
        
        
Answer:
x-intercept: (-5,0)
y-intercept: (0,3)
Step-by-step explanation:
y-intercept: when x = 0
-3(0) + 5y = 15
5y = 15
y = 3
x-intercept: when y = 0
-3x + 5(0) = 15
-3x = 15
x = -5
