Answer:

see explanation

Step-by-step explanation:

(a)

OC = OB ( both radii of the circle )

Thus Δ BOC is isosceles with congruent base angles.

∠ BOC = ∠ BCO = 50°

(b)

∠ ACB = 90° ( angle in a semicircle ), then

∠ ACO = 90° - 50° = 40°

OA = OC ( both radii of the circle )

Thus Δ ACO is isosceles with congruent base angles.

∠ BAC = ∠ ACO = 40°

Multiply. 32√⋅28√⋅3√⋅6√ in simplest radical form, in the box.
PolarNik [594]

Answer:  48\sqrt{7}

Step-by-step explanation:

Given expression, \sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}

= √(4×8)×√(4×7)×√3×√(3×√2)

= √4×√8×√4×√7×√3×√3×√2 ( because √(m×n)=√m×√n)

=√4×√4×√8×√2×√7×√3×√3

=4×√(4×2)×√2×√7×3

=4×√4×√2×√2×√7×3

=4×2×2×√7×3

=48√7

Thus,\sqrt{32} \times \sqrt{28}\times \sqrt{3}\times \sqrt{6}=48\sqrt{7}
