It all depends upon what other things are given If hypotenuse is not given, in cosine or reciprocals are useless. In that case only tan and cot will be equally convenient if adjacent sides are given.
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.
If you use PEMDAS: Parentheses, Exponents, Multiply, Divide, Add, Subtract for order of operations your answer will be 277
9x27+2x31-28
243+62-28
305-28=277
In simple terms, the question is asking how the graph is changing as x decreases, or gets smaller. As we move towards the negatives, the y-values continue to get higher and higher.
This would make our answer "Increases without bound."
Answer:
0
Step-by-step explanation:
The zero is in the "hundred-thousands" place. Zero hundred thousands has a value of zero.
