Question

Find the value of c in the figure below. Round to the nearest tenth.http://cdn.activelms.com/data/042c73b1-ddf5-4fd6-91e7-6c8434228f3d/Geometry%20Images/unit%2012-4%20q9.png

Answer 1

is the correct answer 13.2?

Answer 2

id have to check that one. I cant remember the theorem

Answer 3

i think its 13c = 11*20

solve for c

but im not sure

Answer 4

is that correct @agent0smith ?

Answer 5

@jhonyy9 ?

Answer 6

so i think use the proportionality of sides 20/11 = c/13

or exactly how you ve wrote above

Answer 7

This is what I hate about geometry. Trying to remember all this crap

Answer 8

yea!! me too

Answer 9

i think c must be < 20 on observation

Answer 10

welsh yes i agree your idea that c < 20 but than you see what i ve wrote above so i think will result exactly what you say that c < 20 bc. 20/11 = c/13 from this result tha c < 20

yes ?

Answer 11

the diagram looks approximately to scale

Answer 12

shouldn't that be 13*c = 20*11, in order to get c < 20?

Answer 13

so i ve got 16,9 for c

Answer 14

this result i ve got using formula what you ve wrote there welshfella and yes exactly this is less than 20 - right ?

Answer 15

@welshfella

Answer 16

yes
