Question

Луч BK является биссектрисой угла CBD, угол CBD=54 градусов. Найти угол ABK

Answer 1

Сделаем так что угол AВK И СВК - Смежные углы Значит СВК=180-146=34 СВК ЭТО 1 половина угла CBD значит нужно 34*2=68 Ответ: CBD=68

Answer 2

Given Information:

- The angle CBD is 54 degrees. - The line BK is the bisector of angle CBD.

Solution:

To find the angle ABK, we need to determine the measure of angle CBD and then apply the angle bisector theorem.

From the given information, we know that angle CBD is 54 degrees.

According to the angle bisector theorem, the measure of angle ABK can be found by dividing the measure of angle CBD into two equal parts.

Let's calculate the measure of angle ABK:

1. Divide the measure of angle CBD by 2: - 54 degrees / 2 = 27 degrees.

Therefore, the measure of angle ABK is 27 degrees.
