Answer:
6√3 = x           y =12
Step-by-step explanation:
Since the two sides of the triangles have equal angles then two sides have equal length 
the sum of interior angles of triangles is 180° then the last angle is 60° 
then the triangles have perfect sides of 12
y = 12
to calculate x
sin Ф = opposite/hypothenus
sin 60° = x/12
sin 60° = √3/2
( √3/2 )  x 12  = x
6√3 = x
 
        
             
        
        
        
okay lets foces on question 20. 3/20 
all you need to do is times the dinominator into 100 so 20x5=100 and now you have to multipy the same number that you multiplyed the first one by so 3x5=15 so the anwer would be 15/100 and to put that in a decimal you need to see the number on top witch is 15 so your real ANWSER IS   .15
 
        
             
        
        
        
Answer:
5 units
Step-by-step explanation:
Given:-
- The area of the circle was computed to be A = 78.5
- The value of π is estimated to be = 3.14
Find:-
What is the radius of the circle?
Solution:-
- The area of a circle (A) with radius ( r ) is computed by the following formula:
                             A = π*r^2
- Divide the equation by π :
                             r^2 = ( A / π )
- Take the square root of the entire equation:
                             r = √ ( A / π )
- Substitute the given values:
                            r = √ ( 78.5 / 3.14 )
- Resolve the fraction:
                           r = √25
- The perfect square root of 25
                          r = 5 
Answer: The radius of the circle is r = 5 units
