Answer:
x = 3
Step-by-step explanation:
the midsegment XW is half the sum of the parallel bases , that is
7x + 10 = (46 + 16 ) =
× 62 = 31 ( subtract 10 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
When rotating a point around the origin in clockwise direction, you must always swap the x- and y-coordinates and then multiply the new x-coordinate by -1. In a mathematical language this is as follows:
Since you haven't provide any diagram, I'll use the attached figure below, From here, we have the following points:
So according to our rule, by rotating PQRS 90 degrees clockwise about the origin, we get the new points R':
