Answer:

<u>12º</u>

<u></u>

Explanation:

The angle Marcel's code adjust the shot can be calculated using the cosine law:

$C^2=A^2+B^2-2|A||B|cos(c)$

For the triangle of the figure:

C = 15m
A = 50m
B = 60m
c = ? (the unknown angle)

Substitute and solve for c:

$(15m)^2=(50m)^2+(60m)^2-2(50m)(60m)cos(c)\\\\\\225=2500+3600-6000cos(c)\\\\6000cos(c)=2500+3600-225=5,875\\\\cos(c)=5,875/6000\approx0.97917\\\\c=arccos(0.97917)\approx12\º$
