Answer:
x = 28
Step-by-step explanation:
If AB and CD are the straight lines, sum all the angles formed at a point lying on this line will be 180°.
m∠COE + m∠EOF + m∠FOB + m∠BOD = 180° [Angles at a point O on line AB]
3x + x + (x + 12) + m∠BOD = 180°
m∠BOD = 180° - (5x + 12)
Similarly, m∠AOD + m∠AOC = 180°
152° + m∠AOC = 180°
m∠AOC = 28°
Since, ∠AOC and ∠BOD are the vertical angles,
m∠AOC = m∠BOD
180° - (5x + 12)° = 28°
5x + 12 = 180 - 28
5x = 140
x = 28
Answer:
Up to 5 hours
Step-by-step explanation:
<u>Given:</u>
- One off fee = $46
- Hourly rent = $6.4 / hr
- Amount limitation= $78
<u>Equation to reflect the condition:</u>
- 78 = 46 + 6.4t
- 6.4t = 78 - 46
- 6.4t = 32
- t = 32/6.4
- t = 5 hours max
So, the meeting room can be rented for up to 5 hours with $78
You would of taken 28 dollars away after 7 days because if your taking away 4$ each day you just have to figure out 4 times what equals 28 witch is 7
So the answer is 7 days
