According to exterior angle property,exterior angle of an angle is the sum of other two angles.
So,
According to angle sum property,the sum of angles in the triangle add to 
Answer: The circumference of the circle is 53.38 cm.
Step-by-step explanation:
Circumference of the circle is the distance around the circle.
Formula used:
Where,
C is circumference of circle
r is radius of circle
Given:
Radius of circle = 8.5 cm
Now putting all the given values in the above formula, we get:
Therefore, the circumference of the circle is 53.38 cm.
18 The 2 trapezia formed by midpoint are similar so we can write
19/24 = x / 19
x = 19^2 / 24 = 15.04
19. 360 degrees . This is true for all polygons
Answer:
time = distance / velocity
time = 34,200 meters / 20.1 meters per second
time = 1,701.4925373134 seconds
time = 28.36 minutes
Step-by-step explanation:
