Answer:

see explanation

Step-by-step explanation:

(a)

The angle on the circumference is half the central angle , that is

∠ A = ∠ BOC ÷ 2 = 50° ÷ 2 = 25°

(b)

Δ AOC is isosceles ( OA = OC , radii of the same circle ) then the base angles are congruent , that is

∠ ACO = ∠ A = 25°

(c)

Δ BOC is isosceles ( OB = OC, radii of the same circle ) then the base angles are congruent, that is

∠ BCO = \frac{180-50}{2} = \frac{130}{2} = 65°

(d)

∠ ACO + ∠ BCO = 25° + 65° = 90° ( angle in a semicircle )

Does anyone know the answer?
Helen [10]
The answer would be 60, if you add 13,15, and 12 up you get 40. Those numbers would be considered 2/3 of all the marbles. Divide 40 by 2 to get how many marbles is 1/3. You would get 20 being a third if the marbles. Add that to the original 40 and you’ll get a total of 60.
