when derek planted a tree it was 36 inches tall. the tree grew 1 1/4 inches per year the tree is now 44 3/4 inches tall. how man
mafiozo [28]
Derek would have planted the tree 7 years ago. You subtract 36 from 44.75 and get 8.75. This is how much the tree grew since he planted it. Then, you'll divide 8.75 by 1.25 (1 1/4) which tells you how many years it has been since he planted the tree. The final answer is 7 years. Hope this helps!

Answer:

There is not enough information to prove the congruence

Step-by-step explanation:

There is not enough information to prove the congruence because we would need to be given at least 3 equal elements (angles and sides) between the triangles. But in this problem we are only given the fact that 2 sides are equal in both triangles, which as I mentioned earlier is not enough.
