Answer 5

OH yeah, Ghost 431 is right!!! I am so sorry, I didn't calculate the angle. \[\huge Terribly~sorry\]

Answer 6

SO A IS CORRECT?!

Answer 7

but in the figure given it doesn't show that a is 90?!?

Answer 8

that's my carelessness. Although they didn't name it out, our responsibility is to find it out. That's what Ghost431 did.

Answer 9

shame on me, I delete my wrong answer, hihihi...

Answer 10

since the line "l" is a straight line you get the missing angle by doing 180-85=95
