Answer:
23
Step-by-step explanation:
3.47 = 3 sig. figs.
6.7 = 2 sig. figs.
Since these two numbers are being multiplied, you would round to the smallest number of sig. figs. of the two. In this case, it would be 2 significant figures.
3.47 * 6.7 = 23.249 (dont forget to round to 2 sig. figs. ) --> 23
HUH!!!??
The angle is in the second quadrant.
The cosecant of an angle is the same as the reciprocal of the sine of that angle. In other words, as long as ,
.
Therefore, is equivalent to .
Consider a unit circle centered at the origin. If the terminal side of angle intersects the unit circle at point , then
For angle ,
In other words, this intersection is above and to the left of the origin. That corresponds to second quadrant of the cartesian plane.
