. If a spherical Triangle on Earth has an excess of 30 degrees, find the area of this spherical triangle measured in square miles.
b. If a spherical triangle on the moon has an excess of 30 degrees, find the area of this spherical triangle in sqare miles.
c. Find the ratio of the above answers to a and b.
Confused? What does that mean?
I gave you the formula for area of a spherical triangle given the excess angle, and the radius of the object. re is the radius of Earth. rm is the radius of the moon.
