Answer:
15
Step-by-step explanation:
If this is an arithmetic progression, then there is a common difference.
-3-18 = -21
-21/3 = -7
18 - 7 = x
x = 11
11 - 7 = y
y = 4
4 - 7 = -3
x + y
11 + 4 = 15
If the vertex angle is 28 degrees, then each base angle is 76 degrees. The length of the sides makes no difference.
It would be 20*7 which will give you 140 miles in 7 hours
Two hundred ten thousand and fifty is written as 210,050
Nineteen-hundredths is written as 19/100 or 0.19
So, the whole number is written as 210050.19
Well if it is touching the x-axis, the radius is 3 units.
C = 2 * pi * r = (2)(3.14)(3) = 18.8 or so
