Question

BOC=35° COA=55° BOA=?​

Answer 1

Ответ:

Если это треугольник то:

Объяснение:

BOA=180°-(BOC+COA)

BOA=180°-(35°+55°)

BOA=90°

Answer 2

In the given triangle ABC, you have the angles BOC = 35° and COA = 55°. You want to find the value of angle BOA.

In a triangle, the sum of the angles is always 180°. Therefore, you can use this fact to find the value of angle BOA:

Angle BOC + Angle COA + Angle BOA = 180°

Substitute the given angles:

35° + 55° + Angle BOA = 180°

Combine the known angles:

90° + Angle BOA = 180°

Now, isolate the unknown angle:

Angle BOA = 180° - 90° Angle BOA = 90°

So, the value of angle BOA is 90°.
