Question

in vertical plane p1 making angle 30 degrees with magnetic meridian , apparent angle of dip in vertical plane of dip is 60degrees .The apparent angle of dip in vertical plane p2, which is perpendicular to plane p1 is​

Answer 1

Answer:

in plan 1 30d E d rgrees and 2 is 60 degres and 3is. ---------

Explanation:

sum of two side is 30+60 =90 drgres

and all side is 180 dregres so thrd is 180-90=90 drrees so thrid is 90 dregees

Answer 2

Answer:

The true angle of the dip is

ϕ=30

∘

The angle made by vertical plane p

2

with magnetic meridian is 60

∘

Then the apparent angle of dip is

tanϕ

=

cosθ

tanϕ

Then the apparent dip in the plane is

tanϕ
