if the mean of a and b is 20,the mean of b and c is 24 the mean of a, b and c is 18.what is the mean a and c

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

it would be 3 ÷by 6 because the number on each side
