Answer:
The answer is 10 centimeters
Step-by-step explanation:
If 1 cm on the map = 9 meters. 10cm would be 90 meters. Hope this helps!
Please refer the attached figure for better understanding of the solution
Here we are given that the angle of depression is 40°
And the height of the boat from the water is 25.17 ft
we need to find the length of the rope used which we can take as x
We can see that sin is the ratio that corresponds to the opposite side and the hypotenuse sides of the triangle formed
so we have
sin 40° = ![\frac{25.17}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B25.17%7D%7Bx%7D)
![x=\frac{25.17}{sin 40}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B25.17%7D%7Bsin%2040%7D)
![x=\frac{25.17}{0.6427}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B25.17%7D%7B0.6427%7D)
![x= 39.16](https://tex.z-dn.net/?f=x%3D%2039.16)
Hence the length of the rope needed is 39.16 ft
Answer:
Step-by-step explanation:
1.5= 1 lap+ 0.5 lap = [2(85)+pi*(d)] + [85+pi*d/2]= 3[(85)+pi*d(1/2)]
just substitute d=74
