Question

I need help with E & F, so make sure you explain your answer and show your work!!!! :DDD

Answer 1

Because of the theorem marked above, we can set up this proportion

CI/CR = IO/RE

Answer 2

In this case,


CI = 36+24+30 = 90
CR = 36
IO = unknown for now
RE = 27

Answer 3

90/36 = x/27

Answer 4

good, keep going

Answer 5

90 * 27 = 2430
36 * x = 36x
36x = 2430
x/IO = 67.5cm

Answer 6

good, IO = 67.5

Answer 7

@jim_thompson5910 For NS:
I put 102/36 = x/27 is that right?

Answer 8

yes it is

Answer 9

I got that NS = 76.5cm

Answer 10

very good

Answer 11

thank you very much jim

Answer 12

you're welcome
