Question

Сколько градусов составляет угол ACB который образует хорды AC и BC если дуга BC равна 74 а дуга AS - 116

Answer 1

Дуга АВ =360-(АС+СВ)=360-(116+74)=170 УголАСВ=1/2дугиАВ=170:2=85

Answer 2

Calculating Angle ACB

To calculate the angle ACB formed by the chords AC and BC, we can use the formula:

Angle ACB = 180 - 0.5 * (Arc BC + Arc AS)

Given that Arc BC is 74 and Arc AS is 116, we can substitute these values into the formula to find the angle ACB.

Angle ACB = 180 - 0.5 * (74 + 116)

Angle ACB = 180 - 0.5 * 190

Angle ACB = 180 - 95

Angle ACB = 85 degrees

Therefore, the angle ACB, which is formed by the chords AC and BC, is 85 degrees.
