Answer:
585
Step-by-step explanation:
9 flights = 13 steps
9x13=117 (117 is steps per day)
5x117= 585
The 3 inside angles need to equal 180.
Subtract E from 180 to find the sum of the other two angles:
180 - 104 = 76
Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2
Angle D = 38
