Answer:
m∠7 = 142°
Step-by-step explanation:
Note that a straight line's degree measurement = 180°
Note that the angle directly next to (to the left of) m∠7 has a measurement of 38°. Subtract 38 from 180:
180 - 38 = 142
m∠7 = 142°

This means the radius is 10 units. For it to be a circle, any point that lies on the circle is the same distance from the moving point to a fixed point (the centre). This distance is the radius.
As such, any other point that lies on the circle is 10 units from the centre as well.
Answer:
The exact area is , using the approximation this is 314

Answer:
1.4
Step-by-step explanation:
We want to find the multiplier n such that ...
arc length = n × radius
n = arc length / radius = (9.8 cm)/(7 cm)
n = 1.4
The subtended arc is 1.4 times as long as the circle's radius.
A negative correlation: when the number of years increase the value of the car decrease.
