Which equation can be used to find the area of the blue triangle
A) A= 2(7)(12)
B) A= 1/2(7)(12)
C) A= 2(7 2as exponent)(12 2 as exponent)
D) A= 1/2 (7 2as exponent)(12 2 as exponent)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

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.
