An orange peel may take 1 year to decay to 10-1 of its original mass. An aluminum can may take 50 years to decay to 10-1 of its original mass. a) An orange peel has an original mass of 5 g. What mass will remain after 2 years? b) A metal can has an original mass of 16.5 g. What mass will remain aft er 100 years.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
