Answer: 
Step-by-step explanation:
By definition, the Arc lenght can be calculated with the following formula:
Where "s" is the Arc lenght, "r" is the radius and 
is the central angle measured in radians.
From that equation you can solve for dividing both sides of the equation by the radius "r", then:
According to the information given in the exercise:
And you can identify in the figure that the radius of the circle is:
Therefore, you can substitute values into the equation:
Finally, evaluating, you get the following result:
Rounded to the nearest hundredth of a radian:
Answer:
Yes
Step-by-step explanation:
1 cup= 8/8 cup
1/4 = 2/8
2/8 + 3/8 = 5/8
5/8 is less than 8/8, so they have enough water
The triangle proportionality theorem is
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
So to prove QT parallel to RS, we have to show
Substituting the values, we will get
Which are not equal, therefore the lines are not parallel .
Answer:
100
Step-by-step explanation:
<x is congruent to the angle that measures 100°.
x = 100
Make a proportion, 2/3=120/x. now solve for x, and get betty has 180
