Pe 3 crengi stau 82 de vrabiute . Afla cate vrabiut stau pe fiecare creanga daca pe prima sunt de 3 ori mai multe decat pe a doua iar pe a treia sunt cu 12 mai multe decat pe prima

a 360 degree rotation

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.
