In abc gf=17 in the what is the length of cf

CF = 51

Step-by-step explanation:

Given that ABC is a triangle. D,E, F are midpoints of BC, CA and AB respectively.

AD, BE and CF are the medians of the triangle.  The three medians concur at a point G.  G is the centroid of the triangle.

We know from triangle theorem that the centroid divides each median in the ratio 2:1

Here hence CG:GF = 2:1

Or CG+GF:GF = (2+1):1

So CF: GF = 3:1

Or CF = 3 GF

Since GF = 17 is given we get

CF = 3(17) = 51

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
