Question

In ||gm ABCD, angleA= (y +40)° and angleD= (2y-10)° Find the
magnétude of angleA and angleD. Assign a special name to the
|| gm​

Answer 1

Answer:

In parallelogram, A+ D = 180°

so y+40+2y -10 = 180

3y = 150

y = 50

i.e A = 50+40= 90°

D = 2×50 - 10 = 90°

i.e A = D then it is either Square or Rectangle

Answer 2

Answer:

this answer is correct doood
