Answer:
Step-by-step explanation:
PRQ is the right angle. It is the angle opposite a diameter which is 90 degrees.
PQR is an acute angle. I can make no other statement about it without one more piece of information.
Answer:
162°
Step-by-step explanation:
To convert from radian to degree measure
degree measure = radian measure × 
, then
degree = 
× ( cancel π and 10/ 180 to simplify )
= 9 × 18
= 162°
Might Want to draw this and Its very long but Hope it helped :)
Answer:
The sides are all of the same length - let's say a. The angles are all the same too, and since the angles must add up to 180∘, we conclude that the three angles in the equilateral triangle are equal to 180∘/3=60∘.
Now we do something sneaky. We draw a line all the way down from the top vertex of the triangle to the midpoint of the bottom line.
This new line cuts our equilateral triangle in half. What are the angles in one half?
The angle at the bottom is 90∘.
One of the angles is the same as one of the angles in the original equilateral triangle, so it is 60∘.
So the third angle must be 180∘−90∘−60∘=30∘.
Now the hypotenuse of this new triangle is a, the side length of the equilateral triangle. And the length of the shortest side is a/2, since the line we drew cut the bottom line in half.
Answer:
Range
Step-by-step explanation:
In statistics, the range of a set of data is the difference between the largest and smallest value in the distribution. It is calculated by subtracting the lowest value from the highest value. The range shows how widely spread out a set of given data is.
Answer:
10,000
Step-by-step explanation:
The base for a normal log is 10. You raise the base by the answer, which is 4. 
is 10,000.
