14:16 21:24 28:32 are three ratios that are equivalent
M<ABC = m<EBD = 36 (vertical angles)
78 - x + 36 + 3x - 10 = 180 (straight angle)
Now solve for x
78 - x + 36 + 3x - 10 = 180
2x + 68 = 180
- 68 -68 (subtract 68 on both sides)
2x = 58
x = 29
Answer:
I think the answer would be 3 minutes 32 seconds. I hope this helps.
