1. ## [SOLVED] Bearing

From a point A, the bearing of a radar mast, M, is 048 degree. From a second point B, which is 40 m due east of A, the bearing of the radar mast is 015 degree. Find angle AMB.

My answer is angle AMB=33. Am I right?

correct

3. Hello, mathhomework!

From a point A, the bearing of a radar mast, M, is 048 degrees.
From a second point B, which is 40 m due east of A,
the bearing of the radar mast is 015 degree.
Find angle AMB.

My answer is angle AMB = 33. .Am I right? . . . . Yes!
Code:
      P               Q         M
:               :       *
:               :    * *
:               : *   *
:              *:    *

:  * 42°    90° :*

A      40       B

$\displaystyle \angle PAM = 48^o \quad\Rightarrow\quad \angle MAB = 42^o$

$\displaystyle \angle QBN = 15^o,\:\angle QBA = 90^o \quad\Rightarrow\quad \angle MBA = 105^o$

$\displaystyle \text{In }\Delta AMB\!:\;\angle ANB \:=\:180^o - 42^o - 105^o \;=\;\boxed{33^o}$

4. ## Thank You!

Yeah,~~~Thank you all!
It is really nice that you listed all the steps!
