Find the degree measure of the angle with the given radian measure.
The given radian measure is:
We know that
Thus to find the degrees of the angle multiply the radian measure with
Here the radian measure is not available so when we multiply put
To convert radians to degrees, multiply by :
Put in the expression, we get:
Gateway Arch A plane is flying within sight of the Gateway Arch in St. Louis, Missouri, at an elevation of . The pilot would like to estimate her distance from the Gateway Arch. She finds that the angle of depression to a point on the ground below the arch is .(a) What is the distance between the plane and the arch?(b) What is the distance between a point on the ground directly below the plane and the arch?
