Solve the following.....

Type or write: (show all work) Calculations for the angle through which the Earth rotates. With "A" representing the angle, start with this equation... A = 360 x (time betw. rises or sets)/(86,400 seconds in a day) Use the equation below to calculate "R", the radius of the Earth. FOR FULL CREDIT...Simplify, then solve, then substitute LAST. Convert the measurement for "R" to kilometers (km). "A" is the same angle calculated above. A = Cos-1 [R / (R+H)] COS A = R/(R+H) (R+H) COS A = R Next steps in solving for "R:" - Distribute on left, - then use basic algebra to put all of the terms with an "R" in them on the left - and all of the other non-R terms on the right. - Continue to solve for R
