Answer:
AB = 9
Step-by-step explanation:
Given that line, l is a perpendicular bisector of line segment AC. It intersects line segment AC at point B.
So, we can conclude that AB = BC ............ (1)
Also given that the length of line segment BC is 9.
Now, from equation (1) we can say that, AB = 9.
Therefore, the length of segment AB is 9. (Answer)
Answer: A
Step-by-step explanation:
The angle adjacent to angle 6 is the one we need to find first. To do this, add the measures of the intercepted arcs and divide by 2. 60 + 50 = 110, and half of that is 55. That means that both adjacent angles to the angle 6 are 55 (vertical angles are congruent). The measure of all the angles added together is 360 and angle 6 is vertical to the other "sideways" angle, so they are congruent as well. 360 - 55 - 55 = 250. Split that up between angle 6 and its vertical angle to get that each of those measure 125. Angle 6 measures 125, choice b from above.
Answer: 38.25
Step-by-step explanation: You divide the whole number by the denominator in the fraction.
153/4 = 38.25
