Answer:
The percent error of the scale is 2,5%
Step-by-step explanation:
<h3>First Step</h3>
Calculate the difference (error) between the weight recorded and the actual weight in lbs.
difference = 164 - 160
difference = 4 lbs
<h3 /><h3>Second Step</h3>
Convert the difference into percentage by comparing the difference to the actual weight, then multiplied by 100%
percent of difference =
percent of difference =
percent of difference =
percent of difference = 2,5%
1) Quadrilateral PAST, TX=AX, (given)
2) and (alternate interior angles theorem)
3) (AAS)
4) (CPCTC)
5) PAST is a parallelogram (a quadrilateral with two pairs of opposite congruent sides is a parallelogram)
