Explicación paso a paso:
18) Calcular "x"
Resolvamos:
x = 10 × sen 37 + 10 × cos 37
x = 10 × (3/5 ) + 10 × (4/5)
x = 30/5 + 40/5
x = 6 + 8
x = 14
Por lo tanto, el valor de x es 14
19) Calcular "x"
16 × sen 30 = x × sen 53
16 × (1/2) = x × (4/5 )
(16 × 1)/2 = (4/5 )x
16/2 = (4/5 )x
8 = (4/5 )x
8 × 5 = 4x
40 = 4x
40/4 = x
10 = x
Por lo tanto, el valor de x es 10
20) Calcular "x"
5 × sen 53 = x × sen 45
5 × (4/5 ) = x × (√2/2 )
(5 × 4)/5 = (√2/2 )x
20/5 = (√2/2 )x
4 = (√2/2 )x
4 × 2 = (√2 )x
8 = (√2 )x
8/(√2 ) = x
(8 × √2)/(√2 × √2) = x
(8√2)/(√4) = x
(8√2)/(2) = x
4√2 = x
Por lo tanto, el valor de x es 4√2
Respuesta:
Aplicamos ley de senos.
X/sen98° = 10/sen 45
X= (10X sen 98)/sen 45
X= (10 x 0,99)/0,7
X= 9,9/0,7
X= 14
X/ sen30= 16/sen 53
X= Sen 30x16)/sen 53
X= (0,5 X 16)/ 0,79
X= 8/0,8
X= 10.
X/ sen 53 = 5/sen 45
X= (Sen 53 x5) / sen 45
X= (0,8 x5) / 0,7
X= 4/0,7
X= 5,71
5,7 es igual que 4√2
