Question

Transforme 7 TT/8

rad em graus

Answer 1

$\large\boxed{\begin{array}{l}\underline{\rm Convers\tilde ao\,de\,radianos\,para\,graus}\\\sf Basta\,substituir\,o\,\pi\,por\,180^\circ\\\sf e\,fazer\,os\,c\acute alculos.\\\sf\dfrac{7\pi}{8}\,rad=\dfrac{7\cdot180^\circ}{8}\end{array}}$

$\large\boxed{\begin{array}{l}\underline{\rm Subm\acute ultiplos\,do\,grau}\\\sf 1^\circ=60'\\\sf 1'=60''\\\sf 180^\circ|\underline{8\,\,\,\,\,~~~~~~}\\\sf\!\!\!-\underline{16}~~~~22^\circ30'\\\sf20\\\sf\!\!\!\!-\underline{16}\\\sf4^\circ=240'\\\sf0\end{array}}$

$\large\boxed{\begin{array}{l}\sf\dfrac{7\pi}{8}rad=\dfrac{7\cdot180^\circ}{8}=7\cdot22^\circ30'=154^\circ210'=155^\circ30'\end{array}}$
