PLEASE HELP Calculate the area of the shaded region
1. 72-4pi
2. 36+2pi
3. 144-36pi
4. 48-pi

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)

yeah and

step-by-step explanation:

you know what it isnt great cheating

answer:

step-by-step explanation: easy

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
