Answer:
Option D = 16π/3 ft
Step-by-step explanation:
Arc length formula is written Mathematically as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
So, the arc length is 16π/3 ft
Answer:
2/3
Step-by-step explanation:
4/9+2/9=6/9
then you have to reduce/simply your answer more from 6/9
divide each number by 3 and that with give you your answer 2/3.
6÷3=2 and 9÷3=3
Adding fractions with same denominator
"5 fifths" is equivalent to ' 1 ' . So 5 fifths of anything
is equal to whatever comes after the 5 fifths.
Answer:
Step-by-step explanation:
Supplementary always add up to 180 degrees.
so you can set up the equation like this:
1x+4x=180
5x=180
x=36
now to find the angle measures you plug in the value of x
one angle is 36 degrees and the other is 144 degrees
