Regular polygon can be incribed in a circle of radius equal to its side.
so if you join all the vertices to the centre, you will get 6 equilateral triangles. each interior angle will have 2 angles of 60 each. thus interior angle = 120
exterior angle=180-120=60
$21.00
Step-by-step explanation:
if 1 yard equal 6 dollars
do 6 times 3 = 18
and half of 6 is 3
add 18+3=21 dollars
47 should be your answer.
Answer:
The right triangle: The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.
Do you know the length and height of the field? If you do, all all the sides together (Height + Height + Length + Length) and you get the answer to Part A.
Part B:
Just do 120 times 5. Then, divide your answer by 6. The answer will be the time they need to run each lap in.
Part C:
Again, what is the length? When you know your length, divide it by 2. Your answer is the side length.
Hope that helped. :)
