1)Em que quadrante do círculo trigonométrico está o arco de 1500°:
a) 1°quadrante
b) 2°quadrant
c) 3º quadrante
d) 4°quadrante​

Answer 1

$\large\boxed{\begin{array}{l}\rm 1500^\circ|\underline{360^\circ}\\\!\!\!\!-\rm\underline{1440^\circ}~~4\\\rm~~60^\circ\\\\\rm 1500^\circ=4\cdot360^\circ+60^\circ\\\rm 60^\circ\in\,1^o\,quadrante\\\rm portanto\,1500^\circ\in 1^o\,quadrante\\\huge\boxed{\boxed{\boxed{\boxed{\rm\dagger\red{\maltese}~\blue{alternativa~a}}}}}\end{array}}$
