angles formed by these tosses are
and
degrees to the nearest hundredth.
<u>Step-by-step explanation:</u>
Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.
The Law of Cosines (also called the Cosine Rule) says:

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
The Law of Sines (or Sine Rule) is very useful for solving triangles:

We can now find another angle using the sine rule:
⇒
⇒
⇒
So, the third angle =
Therefore, angles formed by these tosses are
and
degrees to the nearest hundredth.
Answer:
94.2 ft of fencing
Step-by-step explanation:
To answer this, find the circumference, C, of the garden, using the circumference formula C = 2(pi)r.
Here, with r = 15 ft, we get C = 2(3.14)(15 ft) = 94.2 ft of fencing will enclose this garden.
Answer: Choice A
The number line graph is visually showing every number that is 19 or smaller; hence 
Note the use of a closed or filled in circle at the endpoint (in contrast to an open circle). This indicates we are including the endpoint 19 as part of the solution set, and that's why we go for "or equal to" as part of the inequality sign.
