Step-by-step explanation:
Answer:
Bill suffered a loss of 42.85%.
Step-by-step explanation:
Bill bought a home for $210000 and sold it for $120000 and we have to calculate the percentage loss he suffered.
As we know loss suffered = Difference of sale price and cost price of the home.
Total loss = 210000-120000 = $90000
Now percentage loss = 
= 9/21×100 = 3×100/7 = 42.85%
So the answer is 42.85% loss.
2. one angle of and one side are equal therefore bc and ce have to equal each other.
3.because angle a and angle d equal each other, angles acb and dce equal each other
4.opposite interior angles equal each other
5.triangles equal each other for all the reasons above
Sum of all interior angles of a polygon
180( n - 2) where n = number of sides in the polygon
now, if n = 19, the polygon has 19 sides, then 180( 19 - 2)
