The angle measurements in the diagram are represented by the following expressions. A=6x- 35
B = 3x + 53
Solve for x and then find the measure of A:
A=

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

faster, im not sure why but i know it is faster
