In the accompanying diagram, DCFG is tangent to circle O and F, ECH is a secant intersecting the circle at A and B, arcAB=140 and arcAF=160. If m

go on the tube you might find some information there

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

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

you just switch the numbers basically so it would be 3/17
