Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have

Add
to both sides , we have


subtract 3 from both sides , we have

divide both sides by 4 , then

substitute
into equation i to get the value of y , that is



Therefore :
and 
Angle a +angle b = 180 degrees
angle a + angle a + 30 = 180
2*angle a = 150
angle a = 75degrees
angle b = 75+30 = 105 degrees
now, angle b +angle c = 180
so, angle c = 180-105 = 75 degrees
