Answer:
i think 88
Step-by-step explanation:
(it's been a while since I've done this so I'm not too sure it's correct)
The formula we need to use is
2πr(angle/360)
we need the radius (r)
To get r we need angle AES
180-80= 100
using the equation from before
88=2πr*(100/360)
raidus: 50.42
Then to get the length CD we need angle DEC
180-80=100
2π*50.42*(100/360)=88
there probably was some kind of shortcut we could've used to figure this out faster but whatever
Answer:
(86.2,0) is the x-intercept.
Step-by-step explanation:
You can use the slope formula to figure this one out:
Just use two of the points on the table, any of them will work:
Now you have the slope of the equation, now using the y-intercept equation you can substitute the variables for point of the table and the new slope.:
Now just solve for b to get the y intercept:
Now you have the y-intercept so you just have to plug in 0 to the y spot and it will calculate the x-intercept.
And that's the x-intercept.
The area is 448.5
(13 × 29) + (11 × 13)1/2
He rode 3 miles on monday, 10 on tuesday
10+3=13
rode two times farther on wed
so 10x2=20
13+20=33
