Answer:
10/7
Step-by-step explanation:
5 4/7=39/7
x+39/7=7
x=7-39/7
x=49/7-39/7
x=10/7
 
        
                    
             
        
        
        
Answer:
3/5 or 0.6
Step-by-step explanation:
Here, given the value of tan theta , we want to find the value of sine theta
Mathematically; 
tan theta = 0pposite/adjacent 
Sine theta = opposite/hypotenuse 
Firstly we need the length of the hypotenuse 
This can be obtained using the Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides.
Let’s call the hypotenuse h
h^2 = 3^2 + 4^2
h^2 = 9 + 16
h^2 = 25
h = √(25)
h = 5
Now from the tan theta, we know that the opposite is 3
Thus, the value of the sine theta = 3/5 or simply 0.6
