Identify m∠C in the triangle shown. Question 6 options:

A)

17°

B)

23°

C)

21°

D)

19°

C

Step-by-step explanation:

21

it has the same slope and a different y-intercept

hope this : )

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
