Question

plz solve it in English

Answer 1

∠PSR = 110

since its a parallelogram opposite angles will measure same

so ∠PQR = ∠PSR = 110

Now in a parallelogram sum of interior angles = 360 degree

so, Other two angles will be same so lets assume them as x

so, ∠QPS = ∠QRS = x

Now ∠QPS + ∠QRS + ∠PQR + ∠PSR = 360

x + x + 110 + 110 = 360

2x + 220 = 360

2x = 360 - 220

2x = 140

x = 70

so we have all the angles now

∠QPS = 70

∠QRS = 70

∠PQR = 110

∠PSR = 110
