Answer:
180 Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.
0.08.
0.8/10 is 0.08
the answer is 0.08
The answer its “i” because there are two complex square roots of −1, namely i and −i,
check the picture below.
recall that a cube sides are all equal in length, and it's really just 6 squares stacked up to each other at the edges.
so if 600 is the total area of those 6 squares, then just for one is 600/6 in².
