Answer 1

The bearing of B from D is 213.7 degrees

What is bearing?

The bearing of a point from another point is the measure of angle in degrees measured clockwise from north.

The bearing of B from D is calculated as:

$B^o =180 + \angle ADB$

The measure of angle ADB is calculated using the following tangent ratio:

$\tan(\angle ADB) = \frac{30}{45}$

$\tan(\angle ADB) = 0.6667$

Take the arctan of both sides

$\angle ADB = \tan^{-1}(0.6667)$

Evaluate the arctan

$\angle ADB = 33.7\°$

Recall that:

$B^o =180 + \angle ADB$

So, we have:

$B^o = 180^o +33.7^o$

$B^o = 213.7\°$

Hence, the bearing of B from D is 213.7 degrees
