Use notes and youll get an answer
Step-by-step explanation:
Answer:
x + 6x+10 + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10 + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
SOLUTION
Consider the property, opposite angle of a cyclic quadrilateral are supplementary
hence
![\angle NMP+\angle NOP=180^0](https://tex.z-dn.net/?f=%5Cangle%20NMP%2B%5Cangle%20NOP%3D180%5E0)
Recall that
![\begin{gathered} \angle NMP=\angle M=(8x-24)^0 \\ \text{and } \\ \angle NOP=\angle O=(4x)^0 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cangle%20NMP%3D%5Cangle%20M%3D%288x-24%29%5E0%20%5C%5C%20%5Ctext%7Band%20%7D%20%5C%5C%20%5Cangle%20NOP%3D%5Cangle%20O%3D%284x%29%5E0%20%5Cend%7Bgathered%7D)
Hnece, we have that
![\begin{gathered} \angle M+\angle O=180^0(opposite\text{ angles of a cyclic quadrilateral)} \\ (8x-24)^0+4x^0=180^0 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cangle%20M%2B%5Cangle%20O%3D180%5E0%28opposite%5Ctext%7B%20angles%20of%20a%20cyclic%20quadrilateral%29%7D%20%5C%5C%20%288x-24%29%5E0%2B4x%5E0%3D180%5E0%20%5Cend%7Bgathered%7D)
Then
![\begin{gathered} 8x-24+4x=180 \\ 8x+4x-24=180 \\ 12x-24=180 \\ \text{Add 24 t o both sides } \\ 12x-24+24=180+24 \\ 12x=204 \\ \text{divide both sides by 12} \\ \frac{12x}{12}=\frac{204}{12} \\ \text{Then} \\ x=17 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%208x-24%2B4x%3D180%20%5C%5C%208x%2B4x-24%3D180%20%5C%5C%2012x-24%3D180%20%5C%5C%20%5Ctext%7BAdd%2024%20t%20o%20both%20sides%20%7D%20%5C%5C%2012x-24%2B24%3D180%2B24%20%5C%5C%2012x%3D204%20%5C%5C%20%5Ctext%7Bdivide%20both%20sides%20by%2012%7D%20%5C%5C%20%5Cfrac%7B12x%7D%7B12%7D%3D%5Cfrac%7B204%7D%7B12%7D%20%5C%5C%20%5Ctext%7BThen%7D%20%5C%5C%20x%3D17%20%5Cend%7Bgathered%7D)
Hence
x=17
Since
![\begin{gathered} \angle NOP=(4x)^0 \\ \text{substitute the value of x, we have } \\ \angle NOP=4\times17=68^0 \\ \text{Hence } \\ \angle NOP=68^0 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cangle%20NOP%3D%284x%29%5E0%20%5C%5C%20%5Ctext%7Bsubstitute%20the%20value%20of%20x%2C%20we%20have%20%7D%20%5C%5C%20%5Cangle%20NOP%3D4%5Ctimes17%3D68%5E0%20%5C%5C%20%5Ctext%7BHence%20%7D%20%5C%5C%20%5Cangle%20NOP%3D68%5E0%20%5Cend%7Bgathered%7D)
Therefore
The measure of angle NOP is 68⁰
Answer; 68⁰ (The fourth Option )
Answer:
1.01 minutes
Step-by-step explanation:
The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.
Velocity is defined as the rate of change of displacement over time t:
![v=d/t\\](https://tex.z-dn.net/?f=v%3Dd%2Ft%5C%5C)
The function can be expressed to make t the subject to calculate time taken by Bob;
![v=d/t\\\therefore t=d/v, d=304, v=5\\\\t=\frac{304}{5}\times \frac{1}{60}\ min\\\\t=1.01 \ min](https://tex.z-dn.net/?f=v%3Dd%2Ft%5C%5C%5Ctherefore%20t%3Dd%2Fv%2C%20d%3D304%2C%20v%3D5%5C%5C%5C%5Ct%3D%5Cfrac%7B304%7D%7B5%7D%5Ctimes%20%5Cfrac%7B1%7D%7B60%7D%5C%20min%5C%5C%5C%5Ct%3D1.01%20%5C%20min)
Hence, it takes Bob 1.01 minutes to walk the length of the roll.
