Analyze the diagram below and complete the instructions that follow. find the value of a. a.3 b.5 c.8 d.12

option A. 3

Step-by-step explanation:

AS shown for the fight angle triangle

12² = 18 * (a+5)

a + 5 = 12² /18 = 144/18 = 8

a = 8 - 5 = 3

So, the answer is option A. 3

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.
