25mm is the answer if its not tell me
Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.

slope (34-32)= 12-48
slope.2= -36
slope = -18
Answer:
(-4 , 8)
Step-by-step explanation:
The x-axis is the horizontal line. In this case, if you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.
Same with the y-axis. If you are reflecting over the y-axis, you are flipping the sign of the x-coordinate.
In this case, reflect across the x-axis. Flip the sign of the y: (x , y)
(-4 , -8) reflected over the x-axis is (-4 , 8).
