Answer:
Option 3
Step-by-step explanation:
Given:
AB ≅ CD
Point P lies on AB and point Q lies on CD.
∠APO = ∠DQO = 90°
By theorem, if two chords in a circle are equal in measure, then they will be equidistant from the center.
Therefore, OP and OQ will be congruent.
Option (3) will be the answer.
Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036
