Answer:
The angle will be 130 degrees
Step-by-step explanation:
50 at the center translates to 50 at the outer rim.
this means it will be 310-50 divided by 2
260 divided by 2 equals 130
Last one:
In the picture a=2, b=4a, b=4•2=8
1st picture a=3, b=4a, b=4•3=12
2nd picture a=0.5, b=4•0.5=2
3rd picture a=2.5, b=4•2.5=10
4th picture a=4, b=4•4=16, but in the picture b=10 therefore, this rectangular is NOT similar to rectangular ABCD.
Answer:

Step-by-step explanation:
The given sequence is a geometric sequence.
We can find the common ratio using any two consecutive terms of the sequence.

The common ratio is 
9514 1404 393
Answer:

Step-by-step explanation:
The letters designating the end points of the segment may be listed in either order. The symbol over the pair of letters is a bar with no arrows on it.
__
Arrows on the bar over the point names indicate a ray (arrow to the right) or a line (double-ended arrow). This is only a segment, which does not extend beyond its end points.
So based on the given illustration above of different graphs, the graph that depicts a complex number with i as the imaginary part would be the last one, graph D. <span>i as the imaginary part is the same thing as 1i, which makes this one as the answer. Hope this answers your question. </span>
