If the diameter of a circle is 20 in, how long is the arc intercepted by a central angle of 72°?

well the answer to that is xoxoxo

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

answer: 1+1

step-by-step explanation: 1+1 is at least 2
