Answer:
A 13.75
Step-by-step explanation:
because you said the you 1 ponit for every right ans and -0.25 for incorret ans so 15 right ans would give you 15 ponits and 5 incorret ans would give you -1.25 so i add up
15+-1.25=13.75 or 55/4
i did do the math so it is right
33.3
tan A = opp/adj
tan 39° = 27/x
x tan 39° = 27
x = 27/(tan 39°)
x = 33.3
