Answer:
The sum is 2275
Step-by-step explanation:
Given
![75,76,77....99,100](https://tex.z-dn.net/?f=75%2C76%2C77....99%2C100)
Required
The sum
Using arithmetic progression, we have:
![S_n = \frac{n}{2}(T_1 + T_n)](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cfrac%7Bn%7D%7B2%7D%28T_1%20%2B%20T_n%29)
Where:
--- first term
--- last term
![n = T_n - T_1 + 1](https://tex.z-dn.net/?f=n%20%3D%20T_n%20-%20T_1%20%2B%201)
![n = 100 - 75 + 1 = 26](https://tex.z-dn.net/?f=n%20%3D%20100%20-%2075%20%2B%201%20%3D%2026)
So, we have:
![S_n = \frac{n}{2}(T_1 + T_n)](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cfrac%7Bn%7D%7B2%7D%28T_1%20%2B%20T_n%29)
![S_n = \frac{26}{2}*(75 + 100)](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cfrac%7B26%7D%7B2%7D%2A%2875%20%2B%20100%29)
![S_n = 13*175](https://tex.z-dn.net/?f=S_n%20%3D%2013%2A175)
![S_n = 2275](https://tex.z-dn.net/?f=S_n%20%3D%202275)
Answer: False.
Values that are in common with both circles will be inside both circles. These values will be in the overlapping region of the two circles.
Answer:
28 deg
Step-by-step explanation:
Reference angle is the smallest angle formed by the terminal ray, x-axis, and origin. So at 180 you are on the x-axis so just for this question you have to do 180-152=28.
The reference angle should be a positive between 0 and 90 degrees.
