Which would be the right answer???

50 degrees

Step-by-step explanation:

Let's label the angles:

The one near 140 degrees is A.

The 90 angle is B.

The 1 is C.

(They're all interior.)

To find A:

180 - 140 = 40

A = 40 degrees

B is already given.

To find C:

All angles in a triangle add up to 180 degrees so:

40 + 90 = 130

180 - 130 = 50

Therefore:

C = 50 degrees

Hope this helps!

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
