In the shown, midpoints F and G are located with segments CG and DF intersecting at H. If CH = 10 then which of the following is the length of CG?

2 is the final ! : )

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm
