Question

∪AB=86°∪AC=99°Найти: угол BOC и угол BAC.​

Answer 1

Ответ:

Пошаговое объяснение:

∪ВС=360-(∪АВ+∪АС)=360-(86+99)=175°⇒∠ВОС=∪ВС=175° как центральный угол, опирающийся на дугу ВС. ∠ВАС=1/2∠ВОС=175/2=87,5° вписанный угол, опирающийся на ту же дугу, равен половине центрального.

Answer 2

To find the angles BOC and BAC, we need more information about the triangle ABC. The given angles ∠AB = 86° and ∠AC = 99° alone are not sufficient to determine the measures of the other angles.

In a triangle, the sum of all angles is always 180°. So, if we know the measures of any two angles, we can find the third angle.

If you have any additional information about the triangle or any other angles, please provide them, and I'll be happy to help you further.
