A treasure chest things that are right no less than 20 ft./s. The floor of the ocean is at most at -4200 feet. Will the treasure chest reach the ocean floor in the snow three minutes? Explain

No

Step-by-step explanation:

Number of feets per second of treasure chest = 20ft / s

Depth of ocean floor = - 4200

To know if chest will reach ocean depth in 3 minutes ; use the Relation :

Distance = speed * time

Time = 3 minutes = (3 * 60) = 180 seconds

Depth of chest after 180 seconds :

-20 * 180 = - 3600 feets

Hence, chest can't reach ocean floor in 3 minutes

-4200 feets is deeper than - 3600 feets

For this, you need to implement trigonometry, and the soa cah toa method is the one that I use. in this case you would use the tangent, which is toa, opposite over adjacent. in your calculator you will have to click the tan button on your calculator. in the parentheses type in 25 because that is the angle measure that you know. in this case, the side that you don't know is the adjacent side so it would be tan(25)=x/1 (I think it was a 1, it looked like the picture cut it off). this means to isolate the x you need to multiply it by the opposite length (the one on the bottom, 1) and so you need to multiply tan(25) by 1 (or whatever it is on the bottom of the equation/opposite length on the picture). you should get your answer that way and it should be bigger than the opposite side.
