Question

Can someone check answers?

Answer 1

GH/DJ = AB/DC
Is this correct?

Answer 2

yes. your proportion is correct if they are similar pentagons

Answer 3

Thanks. Can you check a few more?

Answer 4

sure. type away

Answer 5

Find the exact length of the altitude drawn to the hypotenuse. Do not round and the triangle isn't drawn to scale.

Answer 6

you should know that altitude of a right triangle is the square root of the product of the two lengths it divides the hypothenuse into.

so in your case, the altidue = sqrt of 9(17)

Answer 7

I got 2 different answers done differently.
First I got 12.36 when I square root 153.
And then I got 3 sqrt 17 (if I did it correctly)

Answer 8

Wouldn't you break down the 9 since it's squared?

Answer 9

yes so 3 sqrt 17 would be your answerr

Answer 10

A survey crew made the measurements shown on the diagram. What's the distance between the 2 campsites? The triangles are proportional.

Answer 11

I tried 82 over 82.8 = 92 over 73.8 and try solving it like that but I wouldn't get a reasonable answer and I left out a variable. So what do I do to solve this?

Answer 12

let FG=x

73.8/ 82 = x/47

try this

Answer 13

I get 42.3 m

Answer 14

ok. that looks right

Answer 15

Would I have to do the same for the other side?

Answer 16

what do you mean?
the question asks you to find FG.
i said that FG=x
so once you foudn what x is which is 42.3

Answer 17

Sorry.
Here's another. Can you check to see if my answer is right?

Answer 18

Find the geometric mean of 5 and 8. Write the exact answer--do not round.
Would it be X = 2 sqrt 5*2?
