primero vamos a calcular el lado faltante usando el teorema de pitagoras para poder obtener el lado faltante a
![a=\sqrt[]{hipotenusa^2-cateto^2}](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B%5D%7Bhipotenusa%5E2-cateto%5E2%7D)
![a=\sqrt[]{100^2-85^2}=52.68](https://tex.z-dn.net/?f=a%3D%5Csqrt%5B%5D%7B100%5E2-85%5E2%7D%3D52.68)
a=52.68 m
teniendo el lado faltante podemos calcular las razones trigonometricas





Step-by-step explanation:

<span>Solve this by substitution:
</span>Solve 5x - 4y = -13 for x:<span><span><span><span>5x </span>− <span>4y </span></span>+ <span>4y </span></span>= -<span>13 + <span>4y </span></span></span>(Add 4y to both sides)
<span><span><u>5x </u></span>= <span><span><u>4y - </u><u>13 </u></span><u> </u> </span></span>(Divide both sides by 5)
5 5
<span>x = <span><span><span><u>4</u></span> y </span>+ -<span><u>13</u><span>
</span></span></span></span> 5 5

5x - 4y = -13, 8x +10y = 12 (enter both equations with a comma between them and it will solve for you and show you step by step.
