Question

3. In Fig. 1233, quadrilaterals are parallelograms Find the degree values of the unknowns, x, y,z.​

Answer 1

Answer:

y=80 degree (Opposite angles of a parallelogram are equal)

80 + x=180

x=100 degree

x=z=100(Opposite angles of a parallelogram are equal)

Answer 2

Step-by-step explanation:

PQRS IS A PARALLELOGRAM

y= R( opposite angles of a parallelogram are equal)

y=80

y+z=180

(sum.of adjacent angles in a parallelogram is 180)

80+z=180

z=180-80

z=100

now z=x(opposite angles of a parallelogram are equal)

x= 100

therefore x= 100 y= 80 and z= 100
