need help finding the angle of a triangle

[tylerik]

I have Triangle ABC with M being the midpoint

A------------M------------B
......_.........X..........._
.........._.....X......._
.............._.X..._
.................C................
distance from C-->B=88cm
distance from A-->B=140cm
distance from M-->B= 70cm
the angle of CBA =132 degrees
the angle of CBM = unknown

I am trying to figure out the angle of CBM ****** There are NO right angle triangles******

Is this possible or will i need to get more points? I am working with robotics and it has been so long since i used trig. I would prefer not to have to find additional points because that requires more coding which == more bugs.

Any help is greatly appreciated!!!

Does that imply M is on AB and is the midpoint of AB?

You have side c (A--B), side a (C-->B), and angle B (angle CBA). Use the law of cosines to find side b (A-->C)

Now you have three sides and an angle. Use the law of sines to find the other two angles

Taking the sketch as shown, M is on AB.

Then mCBA = mCBM = 132°
