Question

In a parallelogram ABCD, if |A = 50°, then the remaining angles respectively are
a) 40°, 140°, 140°
b ) 130°, 50°, 130°
c) 50°, 130, 130°
d) 140%, 40%, 100
solutions send me please​

Answer 1

Answer:

Correct answer is b

Since it is a parallelogram so,

ANGLE A=ANGLE C = 50° ( Opposite sides of a parallelogram are equal)

Angle B = 180-50° ( Co-interior angles)

= 130°

Angle B =Angle D ( Opposite sides of a parallelogram are equal)

Therefore the correct option is B i.e., 130°, 50°, 130°

Answer 2

given,

angleA=50

In a parallelogram angleA=angled

angleB=angleD

sum of consecutive angles are 180

they are angle A+angleB=180

= 50+angleB=180

= angleB=180-50

=130

therefore ,

angleA=50

angleB=130

angleC=50

angleD=130

so c is the answer
