Answer 1

Answer:

PLEASE MAKE ME BRILLIANT

Step-by-step explanation:

2x−7

o

=4x−21

o

(Since opposite angles of a parallelogram are equal)

⇒4x−2x=21

o

−7

o

⇒2x=14

⇒x=7

o

∠D=2x−7

o

=2×7

o

−7

o

=7

∘

∠B=4x−21

o

=4×7

o

−21

o

=7

∘

Now, ∠A+∠D=180

∘

⇒∠A+7

∘

=180

∘

⇒∠A=180

∘

−7

∘

⇒∠A=173

∘

∠C=∠A=173

∘

(Since opposite angles of a parallelogram are equal)

Therefore ∠A=∠C=173

∘

and ∠B=∠D=7
