Answer 1

@Vocaloid

Answer 2

the ratio of legs is the same for each triangle (being similar) so

3x/20 = (4x+2)/28

solve for x

Answer 3

Okay one sec

Answer 4

How would I write that? In equation form?

Answer 5

write what?

Answer 6

This 3x/20 = (4x+2)/28. I know how the other half is written but not the first, because of the dash

Answer 7

Oh

Answer 8

Okay one second lemme do the math

Answer 9

x=10

Answer 10

excellent, that's the ans

Answer 11

Okay, can you help me with a few more?

Answer 12

sure

Answer 14

similar principle as before

Answer 15

10x+15?

Answer 16

the big triangle leg (10+x) corresponds with the small triangle side (x)

the big triangle side (15+42) corresponds with the small triangle side (42)

so (10+x)/(15+42) = x/42, then solve for x

Answer 17

Sorry, I have a hard time knowing where to exactly put each number and equation. I'm terrible at that for labeling XD

Answer 18

\[\frac{ 10+x }{ 15+42 } =\frac{ x }{ 42 }\]

Answer 19

x=28

Answer 20

good, that's it

Answer 22

SSS would make the two triangles congruent not just similar

Answer 23

side-angle-side --> SAS --> first choice

Answer 24

Oh

Answer 25

Last one http://prntscr.com/hxn1cd

Answer 26

if we do a bit of quick math and fill in the missing angles...

Answer 27

the triangle must share all angle sizes making GHK (option 1) the only choice

Answer 28

Oh, dumb me :(

Answer 29

nah, don't call yourself dumb, you're doing a good job ^^

Answer 30

Xd thanks
