Express $\dfrac{6}{\sqrt{245} 3\sqrt{125} 4\sqrt{45}}$ in the form $\frac{A\sqrt{B}}{C}$ where $A$ and $C$ are relatively prime integers, $C$ is positive, and $B$ is not divisible by the square of any prime. Find $A B C$.

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)

the answer is b
