Answer:
c. 12
Step-by-step explanation:
PA² = (BC + PB) × PB => tangent-secant theorem
PA = 8
PB = 4
BC = ?
Substitute
8² = (BC + 4) × 4
64 = 4BC + 16
64 - 16 = 4BC + 16 - 16
48 = 4BC
48/4 = 4BC/4
12 = BC
BC = 12
Answer:
∠ULE = 60°
Step-by-step explanation:
The exterior angle marked 109° is the sum of the remote interior angles marked 49° and x.
109° = 49° + ∠ULE
∠ULE = 109° -49°
∠ULE = 60°
