If `theta_(1)` and `theta_(2)` be the apparent angles of dip observed in two verticle planes at right angles to each other, then the true angle of dip `theta` is given by

A

`cot ^(2) theta = cot ^(2) theta _(1) + cot ^(2) theta _(2)`

B

`tan ^(2) theta= tan ^(2) theta _(1) + tan^(2) theta_(2)`

C

`cot ^(2) theta = cot ^(2) theta _(1) + cot^(2) theta _(2)`

D

`tan ^(2) theta = tan ^(2) theta _(1) - tan ^(2) theta _(2)`
