The measure of the
Answer to Problem 20CE
30°
Explanation of Solution
Given information:
Formula used:
The measure of angles from 0 to 180
Calculation:
Consider the protector postulate:
Any point O between A and H is chosen.
Consider
These rays results in pairing with the real numbers from 0 to 180 in such a way that:
If
From the above figure it can be observe that
Thus,
Therefore, the required angle is 30°.
Conclusion:
The required angle is 30°.
