Question

In the adjoining figure find the size of each lettered angle

Answer 1

Answer:

x=48 y=95 z=37

Step-by-step explanation:

z+143=180

z=37

sum of angles in a quadrilateral is 360

fourth angle in this quadrilateral is 360-143-80-52=85

y+85=180

y=180-85

y=95

x+y+z=180

x+95+37=180

x=180-95-37

x=48
