Un globo sobrevuela una ciudad, Alberto lo observa con un ángulo de elevación de 75°, y David, con un ángulo de elevación de 83°. Alberto y David se encuentran a 3 metros el uno del otro. Calcula a qué distancia a la que se encuentra el globo de cada uno de ellos

if you was gonna solve for a, a is a   < -12

lol.

it's ok we all do this sometimes.

-aparri

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
