Answer:
Total number of edges for resulting solid = 12
Step-by-step explanation:
A wooden block measures 2 inches by 2 inches by 3 inches. A wedge is cut off from each corner of the block by slicing at points that are 1 inch from each corner.
We have to find the number of edges in the resulting solid after we cut the edges as told above.
There are two faces along the height which will become sharpened after we take out the cuts.
So the resulting shape would be like that of a cylinder with its both ends pointed.
So total number of edges = 4 + 4 + 4 = 12

via the angle sum formula of sin


which proves the second choice
the third choice is wrong since for x=0,y=0 it will show that 2=1 which is incorrect
for the fourth one you can do some thing similar to choice one just expand the sum formula of sin and that should be true too
so
the first , the second and the fourth are all true
