What is the equation for the hyperbola shown?
x^2/8^2-y^2/5^2 = 1
x^2/5^2-y^2/8^2 = 1
y^2/8^2-x^2/5^2 = 1
y^2/5^2-x^2/8^2 = 1
answer is d welcome guys

d, its the only one that is possible

Step-by-step explanation:

Answer with explanation:

Suppose a point (a,b) lies on the circle.

To find Sine, Cosine and Tangent values we need to construct a right angled triangle.

So, to Construct a right triangle inside a Circle

Draw a diameter of the circle.Join the end points of diameter to the point lying on the circle.

Angle in a Semicircle is right triangle.

So, Right triangle is constructed.The two sides can be calculated , if end points of diameter is Known and also the hypotenuse which is Diameter of the circle.

Then we can be Evaluate Sine, Cosine and Tangent values.
