Answer:

  • 42°

Step-by-step explanation:

  • The triangle is isosceles as two sides are radius.
  • The central angle and the tangent chord angle refer to same arc.
  • Tangent chord angle is half the size of the central angle.

The central angle is:

  • 2*48° = 96°

The other angles in the triangle are equal:

  • ∠θ = 1/2(180° - 96°) = 1.2(84°) = 42°
