Answer:
x = 9
y = 9√3 = 15.6
Step-by-step explanation:
The triangle given is a right triangle, therefore:
✔️apply trigonometric ratio formula to find x:
Reference angle = 60°
Hypotenuse = 18
Adjacent = x
Thus:
Cos (60) = x/18
Multiply both sides by 18
18×cos(60) = x
9 = x
x = 9
✔️find y by applying pythagorean theorem:
y² = 18² - x² (pythagorean theorem)
y² = 18² - 9² (substitution)
y² = 243 
y = √243
y = √(81*3) 
y = 9√3 = 15.6
 
        
             
        
        
        
Answer:

Step-by-step explanation:
All you do is divide the speed by the distance 12/8=1.5 simple as that
Would be amazing if you marked me brainliest :)
 
        
             
        
        
        
3500(1 + .03/12)^12(5)
3500(1.0025)^60
The answer is:
$4,065.66 or $4,066
Hope this helps :)
