To find: the equivalence relation.

Answer to Problem 15WE
A relation such as “Is as rusty as” that is reflexive, symmetric and transitive is an equivalence relation then “has the same length as” is equivalence relation. Option “b” is correct.
Explanation of Solution
Given information:
Given relations are
- Has rustier than
- Has the same length as
- Is opposite (for rays)
- Is coplanar with (for lines)
Calculation:
Reflexive property: Robot A is as rusty as itself.
Symmetric property: If Robot A is as rusty as Robot B then Robot B is as rusty as Robot A.
Transitive property: If Robot A is as rusty as Robot B and Robot B is as rusty as Robot C, then Robot A is as rusty as Robot C.
A relation such as “Is as rusty as” that is reflexive, symmetric and transitive is an equivalence relation then “has the same length as” is equivalence relation. Option “b” is correct.

Mary reasoned that she could draw a rectangle around the figure so that the point O was at a vertex of the rectangle and that points A and B were on sides of the rectangle. Then she reasoned that the three smaller triangles resulting could be subtracted from the area of the rectangle. Mary determined that she would need 28 square meters of artificial turf to cover the green shaded yard space pictured exactly.arrow_forward7. 11 m 12.7 m 14 m S V=B₁+ B2(h) 9.5 m 16 m h+s 2 na 62-19 = 37 +, M h² = Bu-29arrow_forward
