Question

the measure of angle ABB'​

Answer 1

Answer:

The answer will be 45 deg

First, the slope of BB' is 0. Thus, BB' is perpendicular to the x axis.

Taking point M to be on (5,2), AM is perpendicular to the y axis.

Thus, AM is perpendicular to BB'.

Thus angle AMB is a right angle and so, AMB is also a right triangle.

Now, the slope of AB = 1, and arctan(1) = 45deg.

Thus, the angle ABM = ABB' = 45 deg
