Answer:
c° + 148° = 180° (St. angle)
c° = 180° - 148°
c° = 32°
then,
c° = d° = 32° ( alternative angle)
then,
let's d (crosspounding angle)
d° + 62° = 180° (St. angle
d° = 180° - 62°
d° = 118°
then,
d° = a° = 118° (crosspounding angle)
then,
a° = b° = 118° (vertically opposite angle)

Total Surface Area: 310 sq.in.
50+50+35+35+70+70 (areas of all separate rectangles) = 310.
Answer:
After 15 minutes, they are moving apart at 8100 ft/sec
Step-by-step explanation:
Using the direct proportion
For the man, 4ft/sec
4ft -----1 sec
Xft ----- 60 x 15 sec
X = 3600 ft/sec
For the woman, 5ft/sec
5ft -----1 sec
Xft ----- 60 x 15 sec
X = 4500 ft/sec
After 15 minutes they are moving apart at 4500 + 3600 = 8100 ft/sec
He has 3 red marbles and 8 overall marbles (5 + 3 = 8)
So the ratio would be 3:8
