Question

Sabiendo que: sen (2x - 10 °) csc (x + 30 °) = 1; calcular: J = 5sen (x + 13 °) + 4tan (x - 3 °)

Answer 1

Respuesta:

∴J=7

Explicación paso a paso:

sen(2x - 10°)csc(x + 30°) = 1

2x - 10° = x + 30°

x = 40°

J= 5 sen(40° + 13°) + 4tan(40° - 3°)

J=5sen(53°) + 4tan(37°)

J= $\frac{5x4}{5} +\frac{4x3}{4}$

J= 4 + 3 = 7

∴J=7
