Answer:
Step-by-step explanation:
The angle we are given is 2° and we are given the opposite leg, 135 ft. We are trying to find the hypotenuse length- the diagonal distance from the ship to the lighthouse.
So, we use SOHCAHTOA with sine:
![sin(2)=\frac{opp}{hyp}= \frac{135}{x}](https://tex.z-dn.net/?f=sin%282%29%3D%5Cfrac%7Bopp%7D%7Bhyp%7D%3D%20%5Cfrac%7B135%7D%7Bx%7D)
Keep in mind that the angle is in degrees. Also, the number is large because of the extremely short angle.
5/7 is greater than 4/6 or 2/3
2/3 is 66% or .6 repeated
5/7 is 71.4% or .714285 repeated
therefore 5/7 > 2/3
