We know that
if <span>90° < θ < 180°
</span>then
θ--------------> belong to the second quadrant
so
tan θ is negative
sin² θ + cos² θ=1----------> sin² θ=1-cos² θ----->sin² θ=1-(-2/9)²
sin² θ=1-(4/81)------> 77/81----------> sin θ=√(77/81)------> √77/9
sin θ=(√77)/9
tan θ=sin θ/cos θ------> [(√77)/9]/[-2/9]-------> -√77/2
the answer is the option
<span>A) -77sqroot/2</span>
An exterior angle is an angle supplementary to one of the interior angles.
In other words, an exterior angle is the angle between one of the sides, and the extension of an adjacent side.
In the given diagram, the angle D is measured from one of the sides, but not to the extension of an adjacent side.
Therefore angle D is not an exterior angle.
Option D is the correct one!
Answer:
Step-by-step explanation:
The general equation for a parabola is y=4(x^2). The given eqn is y=x^2.
The equation resembles a parabola.
So clearly the answer is either B or C.
Now substitute some values. The value of y can't be negative because x^2 will always be positive.
The answer is B.
Consider the x-y axis. The x-y- axis is the whole plane, it contains the set of all possible pairs (x, y), where x and y are real numbers.
The set <span>y ≤ 5, includes all those points (x, y) in the plane whose y coordinate is less than or equal to 5. Thus, x can be any number, but y has the restriction
of being at most 5.
According to this discussion, the graph is as in the picture attached. We color the horizontal line y=5, and all points below it.
