In upper delta def, the midpoint of the side opposite vertex d is m and the centroid is c. if dm is 60, what are dc and cm?

Step-by-step explanation:

The midpoint of the side opposite vertex D is M. So DM is a median to the base EF.

We know that,

The centroid cuts every median in the ratio 2:1

Hence,

Given that, the length of DM is 60.

So,

560

hope this : )

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
