Let abcd be a parallelogram. extend bc past b to f, and let e be the intersection of ab and df. if the areas of triangles bef and ade are 1 and 9, respectively, find the area of parallelogram abcd.

which expression represents the approximate length of bc?

step-by-step explanation:

51-50

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

step-by-step explanation:

classify each pair of angles as alternate interior, same-side interior, or corresponding angles.
