How do i find the measure of angle d?

D = 117
because angle 63 = angle 37+a because they are vertical angles,
therefore angle angle 37+a= angle b because they are corresponding angles
so if angle b=63 then angle d=117, so that together they equal 180, a supplementary angle.

Most of the people don’t make the sense of taking it

2.4+3.2t. you get the answer by adding the ones with variables and ones without
