​

Answer 1

Respuesta:

E = 5 / 6

Explicación paso a paso:

Del Gráfico:

Tg φ = a / 3

Tg θ = a / 4

Tg β = a / 2

Tg α = a / 5

Luego:

E = (Tg φ + Tg θ) / (Tg β + Tg α)

E = (a / 3 + a / 4) / (a / 2 + a / 5)

E = a(1 / 3 + 1 / 4) / [a(1 / 2 + 1 / 5)]

E = (1 / 3 + 1 / 4) / (1 / 2 + 1 / 5)

E = [(4 + 3) / 12] / [(5 + 2) / 10]

E = [7 / 12] / [7 / 10]

E = [1 / 6] / [1 / 5]

E = 5 / 6
