Hello, how would I solve this?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

The perimeter of a rectangular lot of land is 436 ft. this includes an easement of x feet of uniform width inside the lot on which no building can be done. if the buildable area is 122 ft by 60 ft, determine the width of the easement. select one: a. 9 feet b. 18 feet c. 4.5 feet d. 7 feet

What is the equation of the line that is parallel to the line with the equation y= -3/4x +1 and passes through the point (12,-12)
