It is m4 in my opinion i’m not sure tho
Answer: b = -6
Step-by-step explanation: First add 10 to both sides to get -3b=18, then divide by -3 to get b = -6.
Hope this helped!

I guess you want the measure of angle <CAB.
The angle ABD is flat thus its amplitude is 180 degrees. Because
<ABD = <ABC + <CBD you get
<ABC = <ABD - <CBD = 180° - 122° = 58°.
In a triangle, the sum of the amplitudes of the angles is 180°. Thus
<CAB + <ABC + <ACB = 180°. You get
<CAB = 180° - <ABC - <ACB = 47°.
