Question

in a trapezium ABCD, AB IS PARALLEL to CD. if ∠A=50°,then ∠D is: a. 110° b. 130° c. 50° d. 120° plss answer!!!!!!!!!!!!!!no spam pls or else i'll report ya!

Answer 1

Answer:

∠D = 130°

Step-by-step explanation:

Since , AB || CD

∠A + ∠D = 180° { sum of co- interior angles of parallel lines is 180°}

Now,

∠A = 50° ( Given )

So, 50° + ∠D = 180°

or ∠D = 130°

Answer 2

Answer:

angle d = 130

Step-by-step explanation:

Since AB।।CD

So then A&D are co-interior angles

Co-interior angles are supplementary

so

Angle D= 180 - A = 180 - 50= 130
