Question

following figures are parallelograms. Find the degree values of the un
'ind the degree values of the unknown x,y,a.​

Answer 1

Answer:

x = 90°, z = y = 60°

Step-by-step explanation:

x= 90° ....(vertically opposite angle are equal)

x+y+30 = 180° (sum of all angles in a ∆ is 180°)

y= 60°

z= y (alternate interior angles are equal)

z= 60°

so, x= 90°, z=y=60°
