Geometry Question (firgure in comments)
Thanks!

1. Is triangle WUX similar to triangle VUY?

Answer 1

Sorry, I think it is based on Similarity of Triangles..

I have no clue how to do that..

Answer 2

okay thanks

Answer 3

How can we find the base for triangle XYZ, I have no clue for this..

Answer 4

this isnt hard

Answer 5

Sorry @perl it is for me....

Answer 6

there is no K in your diagram

Answer 7

if KW/RT=6/5 and the area of triangle QRS= 75cm, calculate the area of triangle XYZ..?

Answer 8

ZW/RT*

Answer 9

so thats your proportionality constant

Answer 10

if ZW/RT = 1.2, then ZW = 1.2*RT

Answer 11

and that goes for all the sides

Answer 12

XZ = 1.2 * QR

Answer 13

Okay.

Answer 14

what is area of triangle QRS

Answer 15

Im super lost sorry, Im not sure how to start to solve for the area

Answer 16

area = 1/2* base * height

Answer 17

area of QRS is 75...

Answer 18

Where did you get 1.2?

Answer 19

use the formula.
1.2 = 6/5

Answer 20

oh okay.

Answer 21

use for the formula for area of a triangle

Answer 22

area = 1/2 *QT * RS

Answer 23

75 = 1/2 * QS * RT

Answer 24

37.5?

Answer 25

now substitute , we know that XY = 1.2 * QS

Answer 26

where are you getting 37.5

Answer 27

Im really lost so 1.2 is all sides of xyz?

Answer 28

@perl I got 108cm!

Answer 29

Is that correct?

Answer 30

lets see

Answer 31

yes

Answer 32

thank you!

Answer 33

so area XYZ = 1/2 (1.2*QS) (1.2*RT) = 1.2^2 * 1/2* QS * RT = 1.2^2 *75
