1 answer:
It is <span>a </span>statistical graph<span> that represents the </span>frequency<span> of values of a quantity by </span>verticalrectangles<span> of </span>varying<span> heights and </span>widths<span>. The width of the rectangles is in </span>proportion<span> to the class </span>interval<span> under </span>consideration<span>, and their areas represent the relative frequency of the </span>phenomenon<span> in </span><span>question. And this is one of example of histogram:</span>

ANSWER :
The answer is :
EXPLANATION :
Note that cotangent is only positive when the angle is in the first or third quadrant.
Since y is not in the first quadrant, it must be in the third quadrant.
So the x and y are both negative.
An angle with a terminal point (x, y)
The cotangent is x/y
We can equate :
Since x and y are both negatives, x = -9 and y = -13
We can have the triangle :
The hypotenuse will be :
We are asked to find the value of sec y.
In an angle with a terminal point (x, y)
The secant is :
The hypotenuse is 5√10 and x = -9
The value of sec will be :
