Step-by-step explanation:
We are given the length of the whole line and its two halves. Since JK and KL make up the line JL, adding them together would make the line JL.
Now we can plug the value of back into the expression we were given for the line KL.
Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ =
Cosθ =
tanθ =
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ =
θ =
Option (A) will be the answer.
Answer:
The answer is
Step-by-step explanation:
Remember that a reflexive relation , where
is the power set of
, is one which conteins the ordered pairs of the form
, for
.
So, As the reflexive and transitive closure of (that we will denote by
) is in particular reflexive, we must add to
the elements
A transitive relation is one in which if the pair
and the pair
are in there, then the pair
must be there too.
So, to complete the relation to be reflexive and transitive we must add the pair
(because
are in
), the pair
, and the pair
because we added the pair
.
Therfore we have that .
