Question

2. A well 1000m deep at an angle of 45 degree, what is the true vertical depth of the well?
​

Answer 1

Answer: 707.11m

Step-by-step explanation:

since the well is at 45 degrees, we can use trig ratios to figure out the vertical depth of the well as u can see image attached.

then since we are looking for the vertical depth and we have information on the hypotenuse we can say

sin45=
`(verticle height)/(1000)`

therefore, we can say.

1000sin(45) = vertical height

hence

vertical height = 707.11m
