OPQRSTUVWX is a regular decagon. A rotation ofdegrees about U maps X to R. Given , find
Two lines and m intersect at O at an angle of . Let A be a point inside the acute angle formed by and m. Let B and C be the reflections of A in lines and m, respectively. Find the number of degrees in .
Equilateral triangle ABC has centroid G. Triangle A'B'C' is the image of triangle ABC upon a dilation with center G and scale factor -2/3. Let K be the area of the region that is within both triangles. Find K/[ABC].
I see you have graph paper.
You must be plotting something
72 degrees is the answer for the first one.
The limit operator is just an excuse for doing something you know you can't.
