Answer:
600 seats
Step-by-step explanation:
We know there is 120 seats on a balcony and that is
of the total seats, we want to find the total number of seats so,
120 seats = 
We know that a whole fraction sums to 1 so for example 
120 seats = 
Multiply both sides to make it a whole fraction
600 seats = 
So if there is 120 seats and that number is only
of the total number of seats then the total number of seats is 600
Step-by-step explanation:
1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.
2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)
3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)
4. that means that ΔADB ≅ΔCDB via SSS rule.
5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)
