Answer:
C. 24 degrees
Step-by-step explanation:
The 3 angles inside ∠ABE: ∠ABC,∠DBC and∠EBD must add to 126 degrees
∠ABC+∠DBC+∠EBD =126
We already know that ∠DBC is 30 degrees, and ∠EBD is 72 degrees, so we can substitute them in
∠ABC+30+72=126
Combine like terms
∠ABC+102=126
Subtract 102 from both sides
∠ABC=24
So, ∠ABC equals 24 degrees, and C is the correct choice
