Question

3. Угол BOD равен 140°. Лучами OA, OC и OE угол разделён на 4 равных угла. Сколько углов по 70° получилось?

Answer 1

3 угла (BOC, AOE, COD)

Answer 2

Given Information:

We are given that the angle BOD is equal to 140° and that the rays OA, OC, and OE divide the angle into 4 equal angles.

Solution:

To find out how many angles of 70° are obtained, we need to determine the measure of each of the 4 equal angles formed by the rays OA, OC, and OE.

Since the angle BOD is divided into 4 equal angles, each of these angles is equal to 140° divided by 4, which is 35°.

Now, to find out how many angles of 70° are obtained, we divide the measure of each of the equal angles (35°) by 70°.

35° divided by 70° is equal to 0.5.

Therefore, we obtain 0.5 angles of 70°.

Answer:

The number of angles of 70° obtained is 0.5.
