Answer:

1) a = 110

2) b = 65

3) c = 115 d= 65 e = 115

How I found the last one?

The whole thing equals 360.

d is equal to 65 so I added those together.

That equals 130. So i subtracted that from 360.

I got 230. Next, I divided that by 2 to get the final 2 angles.

Answer:

a. a and 70º are Supplementary angles (add up to 180º)

Therefore, [tex]a + 70\º = 180\º \Rightarrow a=110\º[/tex]

b. a and 25º are Complementary angles (add up to 90º)

Therefore, [tex]a + 25\º = 90\º \Rightarrow a=65\º[/tex]

c. c and 65º are Supplementary angles (add up to 180º)

Therefore, [tex]c + 65\º = 180\º \Rightarrow c=115\º[/tex]

d and 65º are opposite angles, therefore [tex]d=65\º[/tex]

c and e are opposite angles, once [tex]c=115\º[/tex], [tex]e=115\º[/tex] as well.
