Final 7 - Positive Latitude

Given:

• $\mbox{A 1 m rod casts a 1 m shadow at noon on the summer solstice.}$
• $\mbox{At the equator, the sun's rays strike the earth vertically at 23.5 degrees north.}$

Question:

• $\mbox{What is the latitude at the measurement point?}$

Rationale:

• $\mbox{The triangle with 1 m on both sides is a 45 degree triangle.}$
• $\mbox{90 - The angle at the measurement point} + \mbox{The angle at the equator} = latitude$

Calculate:

• $latitude = 45 + 23.5 = 68.5$
