If angle A and angle B are supplementary, and their measures are (3x + 50)o and (7x + 10)o respectively, find x, the measure of angle A and the measures of angle B.

20 x

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
