Answer 1

@Vocaloid

Answer 2

I've been trying to see if I can mash them up myself. Is it 5/8=x/15?

Answer 3

Still rusty on this that part, but solving is easy XD

Answer 4

almost

you need to make sure the ratio matches the type of side

for example, each triangle has one side next to the angle and one across

Answer 5

5/8 = 15/x

Answer 6

Darn it

Answer 7

x=24

Answer 8

good.

Answer 9

I may need help with some more. Not sure at the moment but I'll give a holler if I do

Answer 10

http://prntscr.com/i0t233 Wouldn't this be the Definition of Congruent Angles since these two are the same figure?

Answer 11

I'd have to think a bit more about this one

Answer 12

Okie dokie

Answer 13

I think I almost have the proof just need to figure out how to prove that BC and AF make 90 degree angles thus proving AA similarity

Answer 14

Well I have this here if it helps http://prntscr.com/i0t7et

Answer 15

yeah that should be congruent angles not angle addition postulate

Answer 16

ADB and CDF are the vertical congruent angles, not BAD and CAD

Answer 17

in the last step you are substituting AC for FC so this is the substitution property of equality not definition of congruent angles

that's it for your proof

Answer 18

Okie dokie, should be just equation steps from here

Answer 20

try to recall the triangle proportionality theorem

AB/BD = AC/CE

find AC. you are given all the other sides

Answer 21

8/10=x/15?

Answer 22

yes

Answer 23

YAY

Answer 24

x=12

Answer 25

good

Answer 26

Excuse my sloppy mouse work http://prntscr.com/i0tc64

Answer 27

judging by the way you have set it up it needs to be 4/x

remember that each ratio must divide corresponding sides

Answer 28

Darn it

Answer 29

x=3

Answer 30

good

Answer 32

notice how in step 4 we are substituting dbc for abd --> substitution property of equality

Answer 33

bae and abd are alternate interior angles (step 5)

Answer 34

step 8 is the triangle proportionality theorem

Answer 35

that's it

Answer 36

So 4 is Transitive Property?

Answer 37

oh yeah (I didn't realize substitution property wasn't a choice) so transitive

Answer 38

XD

Answer 39

Very last one

Answer 40

http://prntscr.com/i0tmrt

Answer 41

Easy

Answer 42

for both ratios write

side across the angle/side next to the angles (it could be the other way around as long as you are consistent with both ratios)

so (2x-1)/9 = 3x/15

Answer 43

x=5

Answer 44

good

Answer 45

Thanks for the help bro. I'll have to tip you someday. When I get money though
