WARNING: Do not, under any conditions, look at the sun, directly or indirectly.The find the elevation of the sun, measure the angle that an object's shadow from the sun makes. One way to do this is with a stick in the ground. Assuming the stick is perpendicular to the ground, the ratio of the stick's length to the shadow's length is the tangent of the angle of elevation. Solve for inverse tangent, and you have the angle.
tan-1(40/30) = 53.13° Therefore, the sun is at a 53.13° angle of elevation.
Any low elevation areas, most notably Phoenix and the surrounding "Valley of the Sun".
If we assume the the flagpole makes a 90 degree angle with the ground, then the angle of elevator for the sun is 34.778°
Angle of elevation: tan-1(100/130) = 37.6 degrees rounded to one decimal place
21metres
Use the tangent angle of elevation which works out as 31.7497 degrees to four decimal places
Angle of elevation = 300/50 = 6 tan-1(6) = 80.53767779 degrees or 800 32' 15.64''
36 degrees
tan(A) = 120/100 =39.81 degrees
Required angle has a tangent of 7.6/6.1 ie 1.249. This is 51.25 degrees.
Use the tangent ratio: tan = 22.5/34 = 45/68 tan-1(45/68) = 33.49518467 degrees Angle of elevation = 33o29'42.66''
