Your answer would be line DC or a have a nice day!
Cosα=x/L
L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:
L=48/cos39 ft
L≈61.76 ft (to nearest hundredth of a foot)
slope = y2-y1 over x2-x1
-1 - 4= -5
-8-0 - -8
so you get -5/-8
negative divided by negative = positive
slope = 5/8
That is 1/23 because that is 1 student out of 23 total students
6+5(9/3)2
6+5(3)2
6+5+6
11+6
17
