Question

прямые AC и CD пересекаются в точке О и сумма углов AOD и COB равна 230 градусов. Чему равен угол AOC?

Answer 1

230/2=115
180-115=65
так как углы вертикальные

Answer 2

Given Information:

We are given that the lines AC and CD intersect at point O, and the sum of angles AOD and COB is 230 degrees. We need to find the measure of angle AOC.

Solution:

To find the measure of angle AOC, we can use the fact that the sum of the angles around a point is 360 degrees. Since angles AOD and COB are given, we can subtract their sum from 360 to find the measure of angle AOC.

Let's calculate it step by step:

1. Sum of angles AOD and COB = 230 degrees. 2. Sum of angles around a point = 360 degrees. 3. Measure of angle AOC = Sum of angles around a point - Sum of angles AOD and COB.

Using the given information, we can calculate the measure of angle AOC as follows:

Measure of angle AOC = 360 degrees - 230 degrees = 130 degrees.

Therefore, the measure of angle AOC is 130 degrees.
