The length of a rectangular envelope is 3 1/2 times its width. A plastic band surrounds the front and back of the envelope to secure it as shown in the picture. The plastic band is 40 3/8 inches long, find the length and width of the envelope.

step-by-step explanation:

c) yes, because of asa or aas

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.
