Given:
A figure of a circle.
To find:
The value of x.
Solution:
Central angle theorem: According to this theorem, the central angle on an arc is twice of the subtended angle on that arc.
Using the central angle theorem, we get


Therefore, the value of x is 70 degrees.
Answer:
80 minutes... or an hour and 20 minutes
Step-by-step explanation:
55+25 = 80. an hour is 60 minutes long
