I Am Struggling With Two Questions :?
This is one of the two

Sine of an angle =

opposite / hypotenuse

I this figure

AB is the opposite which is 12

BC is the hypotenuse which is 13

sine ∅ = 12/13

Therefore the sine ratio of the angle is

12/13

Hope this helps

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
