Agraphic designer makes a sketch for an image that will appear on a poster. the width of the sketch is 9 inches. she figures that it should be enlarged to 350% to make the final image. how wide will the final image be? a. 3.5 in. b. 35 in. c. 31.5 in. d. 315 in.

31.5 in.

is your answer

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)

19.side- angle- side

20. angle- side- angle
