Question 209219
"Altitude"? Perhaps you mean "angle of elevation"
The angle of elevation is the angle (A) formed between the ground and the line-of-sight from the end of the rod's shadow to to top of the rod.
The given ratio of {{{1:sqrt(3)}}} is the tangent of the angle (A) of elevation. To find the angle, take the inverse tangent, often written as {{{Tan^(-1)(A)}}}, (the angle whose tangent is A) which can be found on your calculator.
{{{Tan^(-1)(1/sqrt(3)) = 30}}}
The angle of elevation of the sun is 30 degrees.
The altitude of the sun?...93,000,000 miles?
