That's true; the Law of Cosines works with all triangles. With right triangles it simplifies to the Pythagorean Theorem.
Answer:
198 yards
Step-by-step explanation:
Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.
The total length of stings required for 66 balloons would be;
total length of balloon strings = 66 x 9 feet
= 594 feet
But the string is sold by the yard at the store.
So that,
1 yard = 36 inches = 3 feet
x yard = 594 feet
Thus,
x = 
= 198 yards
x = 198 yards
Therefore, the total length of string that Sean would need is 198 yards.
Answer:
9 + 22h
Explanation:
The question is incomplete as Gordon's height is not given. To solve further, we will represent this height with h
So, we have:
nine more than the 
of 22 and 
More than, in this case means plus (+)
nine + the of 22 and
Rewrite nine as 9 and substitute h for Gordons height
9 + the of 22 and h
product, in this case means multiplication (*)
9 + 22 * h
So, the expression is:
9 + 22h
A. 1800 degrees.
The sum of all the interior angles is 1800 degrees.
In any polygon the exterior angles all add up to 360 degrees.
So it is 1800.
B. 150 degrees,
The interior angles are 150 degrees.
The exterior angles are 30 degrees,
Hence 30•12=360, 150•12=1800.
C. No, not without the use of other regular polygons to fill the gaps in between. So, you can use it to tile a flat surface, but there will be gaps and voids to fill with other tile. Or if you want to get technical, for you tile the plane by congruent regular polygons, there must be polygons meeting at each vertex. Thus the interior angles of each polygon must be 2/, for some positive integer . The vertices always come together at some point. That is, with rectangular tiles there are always groups of 4 tiles, and the 4 corners are 90 degrees each so 4 of them add up to 360. A hexagon has an interior angle measure of 120, and 120 is the greatest factor of 360 (other than 180, which is a straight line, or 360). If you have polygons with 7 or more sides, their corners will not fit nicely to add up to 360 degrees:)
