HELPP asappp anyone!?!

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

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )

What is the solution to the system of equation graphed belowa.(0,-4)b.(2,5),1),-3)
