answer
s=45 units
bc=434 units
explanation
Find the value of s
In a Rhombus all sides are congruent so
AB=BC=CD=DA
AB=9s+29
CD=10s−16
equate AB and CD
9s+29=10s−16
Combine like term
10s−9s=29+16
s= 45 units
the value of s is 45 units
Find the value of side AB
AB=9s+29AB=9s+29
substitute the value of s
AB=9*45+29=434 units
Remember that the sides are congruent
AB=BC=CD=DA
therefore
The length of the side BC is 434 units

Answer:
correct choice is 1st option
Step-by-step explanation:
Two given triangles have two pairs of congruent sides: one pair of length 7 units and second pair of length 8 units. The third side is common, i.e the lengths of third sides are equal too.
Use SSS theorem that states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Thus, given triangles are congruent by SSS theorem.
