Answer:
since angle B and angle C contains the same arc AD. set the angles equal
11x-3=8x+15
x=6
so the angle has a measure of 63 degrees
the central angle is the angle of the arc
and it is always 2 times the angle that we just that contains the arc but does touches the end of the circle.
so its 63 *2 =126 degrees.
(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.
Answer:
Step-by-step explanation:
For this case we have to write the equation of the position of each one.
We have then:
For the robber:

For the marshall
:


By the time the marshall reaches the robber we have:

From here, we clear the time.
We have then:




Answer:
it takes the marshall to catch up to the robber about 2.7 hours.
(1,800−(1,800×0.30))
=1,260
1,260×0.09
=113.4
113.4+1,260
=1,373.4 .....answer
