Please answer correctly

x=10

Step-by-step explanation:

Sense m and n are paralell, the two angles we are given with eqautions have the same answer.

4x-18=3x-8

-3x    -3x

x-18=-8

   +18   +18

x=10

Check:

4(10)-18=22

3(10)-8=22

22=22

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)

i will pick c put check it over to be sure
