Please help me on this question

ans: 80 °

Step-by-step explanation:

given two triangle are isosceles triangle so,

triangle having angle a;

a + 2d = 180

d = 54° ( since a= 72°)

d is vertically opposite to angle of triangle containing x,

similar reason for b ,

hence

x+ d + b = 180

x = 180 - 54 - 46

= 80°

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !

a = 11 : 4

b = 38

c = 1 for every 6
