Use the diagram to find the measure of the given angle. m

Answer:
M is not labelled on the diagram, however, i will solve for all the unknown angles in my explanation.
Step-by-step explanation:
The diagram shows that point "A" is the center point, <CAD = 50° and <DAE = 90° (angle at a right angle).
Therefore:
Total angle on a straight line is 180°, so <EAF = 180° - (50° + 90°) = 40°
<CAD = <BAF (opposing angles), therefore <BAF = 50°
Total angles in a circle is 360°, therefore
<CAB = 360 - (CAD + DAE + EAF + BAF)
<CAB = 360 - (50 + 90 + 40 + 50)
<CAD = 360 - 230
<CAD = 130°
That is all the angles
