Answer:

34. E 2 1/2

36. C 6cm

Step-by-step explanation:

34. ABC's triangle has 4, as it is equivalent to ADE's triangle's 10. I added 4 and 6 because the whole triangle shown is ADE. Then I did 10/4.

36. The reasoning is that on the other side, there is 9cm and 6cm which is equivalent to AB and 4cm

It goes like: 9/6 = AB/4

9 times 4 equals 36, and 36 divided by 6 is 6. Therefore the answer is 6cm.
