Explicação passo a passo:

$\mathsf{a^2 = b^2 + c^2}$

$\mathsf{(25)^2 = 7^2 + (\overline{\rm AB})^2}$

$\mathsf{(\overline{\rm AB})^2 = 625 - 49 }$

$\mathsf{(\overline{\rm AB})^2 = 576 }$

$\boxed{\boxed{\mathsf{\overline{\rm AB} = 24}}}$

$\mathsf{sen\:{\^C} = \dfrac{cateto\:oposto}{hipotenusa}}$

$\boxed{\boxed{\mathsf{sen\:{\^C} = \dfrac{24}{25}}}}$

$\mathsf{cos\:{\^C} = \dfrac{cateto\:adjacente}{hipotenusa}}$

$\boxed{\boxed{\mathsf{cos\:{\^C} = \dfrac{7}{25}}}}$

$\mathsf{tg\:{\^C} = \dfrac{cateto\:oposto}{cateto\:adjacente}}$

$\boxed{\boxed{\mathsf{tg\:{\^C} = \dfrac{24}{7}}}}$
