Answer:

Step-by-step explanation:
We are given:

![interval = [a,b] = [0,2]](https://tex.z-dn.net/?f=interval%20%3D%20%5Ba%2Cb%5D%20%3D%20%5B0%2C2%5D)
Since
⇒ 
Riemann sum is area under the function given. And it is asked to find Riemann sum for the left endpoint.

Note:
If it will be asked to find right endpoint too,

The average of left and right endpoint Riemann sums will give approximate result of the area under
and it can be compared with the result of integral of the same function in the interval given.
So, 

Result are close but not same, since one is approximate and one is exact; however, by increasing sample rates (subintervals), closer result to the exact value can be found.
Answer:
180
Step-by-step explanation:
In this drawing I made, I added some variables. a and d are complimentary, meanwhile b and c are complimentary. A straight line is an angle of 180 degrees. Therefore, a + b = 180.
Answer:
FIND THE HOLE SIZE IN THIS CASE THERE IS NO SIZE SO ZERO IS THE AWNSER
pls can i have brainliest
Hypotenuse^2=12^2+5^2=144+25=169
⇒ hypotenuse =V169=13 cm
No sorry. but if you have ro blox. friend me: Anime_reign123
and If you have discord, friend me: Loner.gurl.07#2244
(i think those are my numbers. try it and lemme know if it works!)
