Question

Determinar “x” en: 3x. tg53º - sec60º = x + 4ctg45º

Answer 1

Respuesta:

3x×tan(53°)-sec(60°) = x+4cot(45°) ; tan(53°) = 1,327

3x(1,327)-sec(60°) = x+4cot(45°) ; sec(60°) = 1,155

3,981x-1,155 = x+4cot(45°) ; cot(45°) = 1

3,981x-1,155 = x+4(1)

3,981x-1,155 = x+4

(3,981-1)x-1,155 = 4

2,981x-1,155 = 4

2,981x = 4+1,155

2,981x = 5,155

2,981x/2,981 = 5,155/2,981

x = 1,729 ( Aproximadamente )
