The question asks us to find m∠ABC. We know that ray BD is a bisector of ∠ABC. So, all we need to do now is equate the expressions of ∠ABD and ∠DBC to the expression of ∠ABC. Here is what we get from this:
Now, just solve for x. When doing so, we get the answer x = 3. Since we have the value for x, all we need to do is plug in that value to the expression for ∠ABC, which would result in 46. This means that the answer to your query is ∠ABC = 46°. Hope this helps and have a phenomenal day!

Step-by-step explanation:
We can first find the equation of the line in point-slope form. The slope of the line is given by , which is (-5-(-3))/(1-(-2)), or -2/3. The equation for a line in point-slope form is
where
is the slope and
is a point on the line -- in this case, we may use (1, -5). Therefore, the equation for the line is y + 5 = -2/3 (x-1).
The question asks for the equation of the line in standard form -- which is . We can get this by simplifying the equation above to get
