Find the arc of the semicircle(diameter is 12)

Step-by-step explanation:

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

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
