Can you someone answer this with solution

A. . . . . . . . . .

I can’t do that check mark thing so I’ll use ! instead.

!12+2!8-12!2

!12 2!8

2!3+2!8-12!2

!8 2!2

2!3+2x2!2-12!2

2x2!2 4!2

2!3+4!2-12!2

2!3+(4!2-12!2)

2!3-8!2

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 know the answer is 3
