Answer:
tan θ = opposite / adjacent
tan θ = 65 / 30
tan θ = 2.1667
Now, we can use the inverse tangent (tan⁻¹) function to find the value of θ:
θ = tan⁻¹(2.1667)
θ = 65.13° (rounded to two decimal places)
Therefore, the angle of elevation of the sun from the tip of the shadow is approximately 65.13 degrees.
