Wait I just did this today let me go get the answers
Since they are similar both dimensions would have the same ratio. The ratio of 5 and 15 is 3. 15 is 3 times larger than 5, so the unknown dimension is 3 times larger than the known dimension.
3 x 10 = 30
The unknown dimension is 30
Answer:
a. Portrays the case of two triangles being equal if two angles and the line between them are equal
b. The case of two triangles being equal when two of their lines are equal, compared 2 by 2 and the angles between them are equal

(45 gal/day) x (31 day/Dec) =
(45 x 31) (gal/Dec) = <em>1395 gallons</em> per December .
Choice-B is closer to that figure than Choice-A is,
but they're both poor estimates.
To work this out you need to do 80 - 64 - 4.16 = 11.48
he received $11.48 change
