I need help with geometry
1 answer:
9514 1404 393
Answer:
A
Step-by-step explanation:
Attached is a copy of the figure with some of the clutter removed. The congruent angles marked with a single arc, and the parallel lines are given.
The angles marked with a double arc are congruent because they are alternate interior angles where transversal XZ crosses parallel lines XW and YZ. Of course, side XZ is congruent to itself.
Hence we have two angles and a side not between them that are congruent. We can declare ∆XWZ ≅ ∆ZYX by the AAS postulate. (choice A)

The partial sum of a geometric sequence is
In your case a=3, so if we sum N terms of the sequence we have
We want this to me more than 1 million, so we have
Considering the log (base 3) of both sides, we have
So, starting from N=13, the sum of the first N terms will be more than 1 million
