Question

I need help with C, E, & F, but first check if A, B, & D have correct answers and measurements. Thank you so much! :D

Answer 1

A, B, D are all correct, good work

Answer 2

work the other three out in basically the same way, similar triangles have equal ratios for coresponding sides, except this time use RE=27cm

Answer 3

Can you work out C for me as an example?

Answer 4

36/27=(36+24)/AT

Answer 5

explain what you did

Answer 6

Well the triangles CRE, and CAT are similar,

side CR corresponds with CA,
and side RE corresponds with side AT,

So the ratio of CR:RE = CA:AT

Answer 7

36/27 = 36 + 24 over x

Answer 8

is that what you mean

Answer 9

yes

Answer 10

Help me with E

Answer 11

the method is the same,

Answer 12

a person confused me about it

Answer 13

set up the ratio equations with the relevent sides lengths, then subsitute the length in (from the diagram ), and if it helps set the unknown length to be x, them solve for x
