The standard equation of an ellipse is:
(x-h)²/a² + (y-k)²/b² = 1
Since the center at the origin, then h = k = 0
The height of this ellipse = 8 units and the width = 4 units, that means the major axis is b (=8) and the minor axis is a (=4)
Then the equation becomes:
x²/16 + y²/64 = 1
Given:
In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.
To find:
The measure of ∠P to the nearest degree.
Solution:
According to the law of cosine:

Using law of cosine in triangle NOP, we get

Putting the given values, we get




Taking cos inverse on both sides, we get



Therefore, the measure of ∠P is 33°.
