Answer:
d- m<1 = 58
Step-by-step explanation:
To find this answer we have to do multiple steps.
So we know that vertical angles are congruent by the definition of vertical angles, <u><em>look at the picture</em></u>
So, we also know that a triangle =180 degrees
therefore we can add 32 and 90 to find the 3rd angle measure
32+90=122, then 180(because that's the total of the triangle)-122=58
So, m<1=58 degrees
