Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.

Answer:
B
Step-by-step explanation:
The pattern is x/-3
It's a conversion. Since it's kilometers to meters, you can just multiply it by 1000 (1000m in 1 km) to get 322000m/hr
