Step-by-step explanation:

hope this helps :)

Here's the solution ~

Let's use Angle sum property of a triangle :

The value of x is 28°

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:
