Triangle DEF has side lengths of 8 cm, 10 cm, and 9 cm. Use the relationship between the sides and angles of a triangle to match each side with its correct length.

linear

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

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
