Toni measured the height of her bedroom doorway with a measuring tape. she measured the height as 171 cm. the doorway’s actual height is 182.8 cm.
what is the percent error in toni’s measurement? round to the nearest tenth of a percent, if necessary.
a.
0.12%
b.
6.5%
c.
6.9%
d.
11.8%

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
