Answer:

16.66°

Por el teorema de Pitágoras:

H² =  C1² + C2²

(14,36)²= (3,2)²+C2²

Donde despejando C2²= (14,36)²-(3,2)²

                                C2²= 195.9696

                                 C2= 13.9989142436119

Entonces Cos α = (2+13.9989142436119)/16.7

                 α = arc cosen [(2+13.9989142436119)/16.7] = 16,66°
