Frequently oil deposits are located where it is impractical to place a drilling rig. for example, a deposit might be 1,834 feet under a busy downtown intersection. to get to the oil a slant well is drilled from some accessible location. if the accessible location is 1,945 feet away, at what angle of depression should the well be drilled to hit the oil deposit? how much pipe will be needed to reach the deposits?

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
