Find the value of x. Then, find the measure of each angle. In triangle A B C, vertex A is at the bottom left, vertex B is at the bottom right, and vertex C is in the middle at the top. The sides can be traced as follows in the counterclockwise direction starting at vertex A: to the right, up and to the left, down and to the left. The angles are labeled as follows: A, 3 x; B, 5 x; C, 4 x.

step-by-step explanation:

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.
