Answer:
∠72°.
Step-by-step explanation:
If a circle has a circumference of 20 and an arc with a length of 4, we can simply set up a ratio to determine the angle of the arc in degrees:
Cross multiply:
Divide both sides by '20':
x = 72°.
Therefore, the measure of the central angle of the arc is ∠72°.
Answer:
it's the second one a rhombus is a diamond
Solve by using the quadratic formula.
x=1+-i√5 / 6
One seventh of 14 = 9.8 and half of 36 is 18 so half of 36 is larger
