Question

Fan and medal please help.show steps involved.

Answer 1

`angle f = 60` because vertical angles are congruent

`angle c = angle f` because corresponding angles are congruent

`angle c = 60` by transitive property

Answer 2

`60 + angle d + 45 = 180` as linear pair angles are supplementary

solve `angle d`

Answer 3

can you ?

Answer 4

How do I get started?

Answer 5

from the last step, you have an equation :
60 + `angle d` + 45 = 180

Answer 6

Wouldn't angle do be the same as angle f?

Answer 7

nope. you need to solve above equation

Answer 8

180-105=75 as angle d?

Answer 9

You got it!

Answer 10

60 + `angle d` + 45 = 180

`angle d` + 105 = 180

`angle d` = 75

Answer 11

yes

Answer 12

Thank you for the help much appreciated
