Answer 1

Well a triangle must have the same angles and proportionate sides to be similar.

The original image has sides 5 : 12 : 13

A is 6 : 8 : 10
B is 15 : 36 : 39
C is 2.5 : 6 : 6.5
D is 12 : 35 : 37

Out of them all I'd say A is the only one that doesn't fit.

Answer 2

JUST A ?

Answer 3

TriangleRST is similar to triangleWXY .

Which statement is a proportionality statement for the ratio of the sides of the triangles?

https://static.k12.com/nextgen_media/assets/1077641-HS_GMT_L2_S2_03_03_qz_Q4.gif

A. RS/XY = ST/WX = TR/YW

B. RS/WX = ST/YW = TR/XY

C. RS/WX = ST/XY = TR/YW

D. RS/YW = ST/XY = TR/WX

Answer 4

B fits if you multiply it by 3
C fits if you divide it all by 2
D does NOT fit either.

If you were able to select A and D select D as well

Answer 5

For the second question:
You gotta make the sides of the left triangle match the right triangle




I think C fits it

Answer 6

Answer 7

You gotta find this:

Answer 8

I think B fits it

Answer 9

△ABC is similar to △LMN. Also, angle B measures 35° and angle C measures 95°.


What is the measure of angle L?



Enter your answer in the box.


_______°

Answer 10

also just b right ?

Answer 11

Yeah

Answer 12

So if ABC is similar to LMN then
A corresponds with L
B corresponds with M
C corresponds with N

So angle L = angle A
It says B = 35 and C = 95

Can you find A?

Answer 13

yes

Answer 14

so it's 50

Answer 15

Yeah. So there's your answer

Answer 16

△ABC is similar to △LMN. Also, sideAB measures 5 cm, sideAC measures 7 cm, and sideL​M measures 35 cm.


What is the measure of sideL​N ?



Enter your answer in the box.


______ cm

Answer 17

okay so
AB corresponds with LM
BC corresponds with MN
CA corresponds with NL

You can make this equation:
\[\frac{AB}{CA}=\frac{LM}{LN}\]
which is
\[\frac{5}{7}=\frac{35}{LN}\]

Are you able to solve that?

Answer 18

49

Answer 19

yeah
