Question

me ayuda por favor :(​

Answer 1

Respuesta:

1. $\alpha$ - $\beta$ = 90

2. 3x + 5x - (-7x) = 360 ----- 15x = 360 ---- x = 24

3. E = $\frac{\frac{1}{\sqrt{3} } . 2 - \frac{3}{5} . \frac{\sqrt{3} }{2} }{\frac{1}{2} } = \frac{11\sqrt{3} }{15}$

4.   $\frac{3x}{5x-2}=\frac{3}{4} \\ \\ 12x= 15x -6 \\ \\ 3x = 6 \\ \\ x=2$ ---- senθ = 2/10 = 1/5

5. x = n sen$\alpha$ sen$\beta$
