Question 1186004
.
If m-angle ABC= 85 and m-angle ABD= 37, find the m-angle CBD.
~~~~~~~~~~~~~~~



As the problem is worded,  printed and presented,  it admits two solutions and two answers,

which means that the problem is posed  INACCURATELY.



If the ray  BD  is inside angle  ABC,  then the measure of the angle  CBD  is the difference    85° - 37° = 48°.



If the ray  BD  is outside angle  ABC,  then the measure of the angle  CBD  is the sum    85° + 37° = 122°.



What happens in reality,  the reader  CAN  NOT  know from the given post.



Professionally written and presented  Math problem will  NEVER  admit such uncertainty.
