Out of 210 racers who started the marathon, 185 completed the race, 18 gave up, and 7 were disqualified. What percentage did not complete the marathon?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

he answer is x=1x3 because x=1 to x=3
