Sun's angle at latitude 42°

High school · ●○○○○ 10 pts

A building is located at latitude 42∘42^\circ. Using Angle of sun=90∘−latitude+(−23.5∘)⋅cos⁡[(N+10)⋅360∘365],\text{Angle of sun} = 90^\circ - \text{latitude} + (-23.5^\circ)\cdot\cos\left[(N+10)\cdot\frac{360^\circ}{365}\right], where NN is the day of the year, find the angle of inclination of the sun on March 10th, the 69th day of the year. Round to two decimal places.
