For this case we must simplify the following expression:

So, solving the first parentheses we have:

We have to:

We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:

Finally, the simplified expression is:

Answer:
Step-by-step explanation:
Statements Reasons
1). M is the midpoint of segment AB 1). Given
B is the midpoint of segment MD
2). AM = MB and MB = BD 2). Definition of midpoint
3). MD = MB + BD 3). Segment Addition Postulate
4). MD = MB + MB 4). Substitution property of of Equality
5). MD = 2MB 5). Simplify
Therefore, if M is the midpoint of segment AB, B is the midpoint of MD then MD = 2MB
Answer:
Yes did is go for it
Step-by-step explanation:
The length of the arc cannot be found without knowing some linear measure of the circle. None are given.
The measure of arc AB is twice that of angle APB, so is
2*108° = 216°.
The measure of arc APB is the difference between that and 360°, so is
360° -216° = 144°.
