i cant see the lines clearly, soo all i can say is that:

- x is the horizontal line, y is vertical

- quadrant I all positive

- quadrant II x negative, y positive

- quadrant III all negative

- quadrant IIII y positive, y negative

- for every line the point passes, it counts as 1

- each point does not have a certain order to go in the chart

sorry, but this is the best i can do for now! make sure your pictures are clear next time :D

we know, that the angle formed by an arc at the center of the circle is two times the angle formed by same arc on any point on the circumference,

So,

$angle \: 1 = 2 \times angle \: 2$

hence, correct answer is B.

${\boxed{\mathcal{\purple{D.\:81}}}}$ ✅

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

$( {3})^{ \frac{11}{5} } \div {3}^{ \frac{ - 9}{5} } \\ \\=( {3})^{ \frac{11}{5} - ( \frac{ - 9}{5} ) } \\ \\ = ( {3})^{ \frac{11}{5} + \frac{9}{5} } \\ \\ = ( {3})^{ \frac{11 + 9}{5} } \\ \\ = ( {3})^{ \frac{20}{5} } \\ \\ = ( {3})^{4} \\ \\ = ( \: 3 \times 3 \times 3 \times 3 \: ) \\ \\ = 81$
