Now, if you notice the picture, the arcRSQ is 280°, since a circle has a total of 360°, then the arcRQ is 360° - 280°, or just 80°.
keeping in mind that arc's get their angle measurement from the central angle they're in, well, in this case the central angle for arcRQ is ∡ROQ, sor ∡ROQ = arcRQ.

Answer:
You should <u>carry 2 other batteries.</u>
Step-by-step explanation:
If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.
The battery inside the flashlight has probably already spent much of its half-life.
We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.
Which means that the average life of that battery is wearing out.
It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.

Answer:
The area of triangle is 120 cm².
Step-by-step explanation:
First, you have to calculate the height of the triangle using Pythogorem Theorem :
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20)
Let a = base = 10 cm,
Let b = height = h cm,
Let c = hypotenuse = 26 cm,
![{10}^{2} + {h}^{2} = {26}^{2}](https://tex.z-dn.net/?f=%20%7B10%7D%5E%7B2%7D%20%20%2B%20%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7B26%7D%5E%7B2%7D%20)
![{h}^{2} = {24}^{2} - {10}^{2}](https://tex.z-dn.net/?f=%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7B24%7D%5E%7B2%7D%20%20-%20%20%7B10%7D%5E%7B2%7D%20)
![{h}^{2} = 576](https://tex.z-dn.net/?f=%20%7Bh%7D%5E%7B2%7D%20%20%3D%20576)
![h = \sqrt{576}](https://tex.z-dn.net/?f=h%20%3D%20%20%5Csqrt%7B576%7D%20)
![h = 24 \: cm](https://tex.z-dn.net/?f=h%20%3D%2024%20%5C%3A%20cm)
We have found out that the height is 24 cm. Next, we have to use the area of triangle formula :
![area = \frac{1}{2} \times base \times height](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20base%20%5Ctimes%20height)
Let base = 10cm,
Let height = 24cm,
![area = \frac{1}{2} \times 10 \times 24](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2010%20%5Ctimes%2024)
![area = \frac{1}{2} \times 240](https://tex.z-dn.net/?f=area%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20240)
![area = 120 \: {cm}^{2}](https://tex.z-dn.net/?f=area%20%3D%20120%20%5C%3A%20%20%7Bcm%7D%5E%7B2%7D%20)
