Answer:

Hence, the value of z is -39/7.

Step-by-step explanation:

$\sf \leadsto \dfrac{z + 9}{3(z + 5)} = -2$

$\sf \leadsto \dfrac{z + 9}{3z + 15} = -2$

$\sf \leadsto z + 9 = -2(3z + 15)$

$\sf \leadsto z + 9 = -6z - 30$

$\sf \leadsto z + 6z = -30 - 9$

$\sf \leadsto 7z = -39$

$\sf \leadsto z = \dfrac{-39}{7}$

Answer:

Step-by-step explanation:

Triangles by definition have 3 sides. If the sides are corresponding then it is beneficial to us if they are the same length as well. If all 3 sides in one triangle are equal in length to the corresponding sides in another triangle, then the triangles are congruent by SSS (side-side-side). This is the case for us. Side EC is corresponding and congruent to side AC; side CD is corresponding and congruent to side CB; side ED is corresponding and congruent to side AB.
