Answer:

x = 2

Step-by-step explanation:

$\frac{x}{x+1} =\frac{2}{x+1}$

x ≠ 0

x ≠ - 2

x ≠ - 1

$\frac{x}{x+1}(x+1) =\frac{2}{x+1}(x+1)$

x = 2

Answer:

Step-by-step explanation:

1. x -> opposite side of 48°

o → hypotenuse

b → adjacent side of 48°

$\sf Sin \ 48^\circ = \dfrac{opposite \ side }{hypotenuse}\\\\\\0.7431 = \dfrac{15}{o}\\\\\\0.74 * o = 15\\\\\\ o = \dfrac{15}{0.74}\\\\\\$

o = 20.27

$\sf cos \ 48^\circ = \dfrac{adjacent \ side }{hypotenuse}\\\\\\0.67 =\dfrac{b}{o}\\\\\\0.67=\dfrac{b}{20.27}$

b = 0.67*20.27

b = 13.58

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2) i → opposite side of 25°

n → adjacent side of 25°

$\sf Sin \ 25 =\dfrac{i}{t}\\\\\\0.42=\dfrac{i}{30}\\\\\\0.42*30=i$

i = 12.6

$\sf Cos \ 30^\circ =\dfrac{n}{t}\\\\0.91=\dfrac{n}{30}\\\\\\0.91*30 = n$

n = 27.3

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3) a → opposite side of 70°

e → adjacent side of 70°

$Sin \ 70^\circ =\dfrac{a}{l}\\\\0.94 =\dfrac{a}{25}\\\\0.94*25=a$

a = 23.5

$\sf Cos \ 70^\circ =\dfrac{e}{l}\\\\0.34=\dfrac{e}{25}\\\\0.34*25=e$

e = 8.5

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$\sf Sin \ 52^\circ = \dfrac{x}{75}\\\\0.79*75=x\\$

x = 59.25

$\sf Cos \ 52^\circ = \dfrac{z}{75}\\\\0.62*75 =z$

z = 46.5
