Both circle a and circle b have a central angle measuring 140°. the ratio of the radius of circle a to the radius of circle b is 2 3 . if the length of the intercepted arc for circle a is 3 4 π, what is the length of the intercepted arc for circle b?

the answer is 9/8pi or D

Step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
