Mark is in training for a bicycle race. he needs to ride 50 kilometers a week as part of his training. he rode 18.23 kilometers on monday and 13.94 on wednesday. how much more does mark need to ride to complete his training for the week a. 4.29 b. 17.83 c. 31.77 d. 36.06

Mark has to ride 50 kilometers. He already rode 18.23 and 13.94.

18.23km+13.94km=32.17km

50km-32.17km=17.83km

Mark will have to ride 17.83km more. The correct answer is B.

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)
