Anytime you have a triangle (right triangles are preferred) where at least 2 angle measures and 1 side is known. Or, at least two sides and 1 angle measure.
OR..... 3 sides or three angles are known. So, sines or cosines could be used at almost anytime to find the sides and angles of a triangle!
Answer:
Step-by-step explanation:
The rate of change of the linear relationship is -1.
Explanation:
It is given that there is a linear relationship between all these points, these points lie on a straight line.
The equation to find the slope passing through two points 
and 
is given by
Substituting the points 
and 
, we get,
Thus, the slope is -1.
Thus, the rate of change of the linear relationship is -1.
For this, we will be using the pythagorean theorem, which is 
. Since we have the hypotenuse and one of the legs, we can solve for the other leg. Our equation will look like this: 
Firstly, solve the exponents: 
Next, subtract 3600 on both sides: 
Next, square root both sides, and your answer will be x = 80 units
Answer :
The Correct Option is B) Hexagon
Step-by-step explanation :
Let number of sides in a polygon be n
The triangles are created by drawing the diagonals from one vertex to all the others.
Since there is no overlapping of the triangles so no diagonal will be drawn back to itself, and the diagonals to each adjacent vertex would lie on top of the adjacent sides, therefore number of diagonals from a single vertex is three less the the number of sides, or n - 3 and the number of triangles is one more than that, so n - 2.
⇒ Number of triangles = number of sides in polygon - 2
⇒ Number of triangles = n - 2
⇒ n = 4 + 2
⇒ n = 6
And the polygon containing 6 sides is called Hexagon
Hence, the correct Option is B) Hexagon
