Answer: x = 70
y = 20
z = 50
Explanation:
x = 90 - 20 , check the Line A and E , it is an L shape, that means it is a right angle which is 90 , and part of it is already 20 , to get the remaining just subtract 20 from 90,which gives the value of x.
Also, check the line AD and CF , they meet at a point , they formed something line multiplication sign, this is called vertically opposite angle which means they are equal , that is why y = 20.
To get Z , the addition of all the angles must sum up to 360 , since sum of angle in a circle is 360 , that's why z = 50
