Question

Solve for angle D using all three of the definitions of vertical, supplementary, and corresponding angles. Explain your reasoning.

Answer 1

where is angle D?

Answer 2

a is 60 because of corresponding angles

Answer 3

the rest is easy do you recall how many degrees is on a line?

Answer 4

180, right

Answer 5

yes now can you find d?

Answer 6

would d also be 60 degrees since it is just a mirror image of a?

Answer 7

no the line consists of d, 45 degrees and a
all of these make up a straight line which means they add up to 180 degrees
a is a corresponding angle and is 60

Answer 8

a and d are not vertical angles

Answer 9

d would be 75

Answer 10

notice 2 angles that add up to 180 are called linear pairs since they are a pair of angles on a line

Answer 11

ye d is 75

Answer 12

Thank you so much!

Answer 13

look for the letter F when looking for corresponding angles

Answer 14

sorry I meant yes d is 75 earlier

Answer 15

F can appear in these fashions as well they are called corresponding angles
