Adjacent angles of parallelogram are of measure 2x and 7x find the value of ‘x’ About the author Melanie
Answer: The adjacent angles are given as (2x+7) ∘ and (3x−2) ∘ . Since, the sum of the adjacent angles of a parallelogram is 180 ∘ , then, 2x+7+3x−2=180 5x+5=180 5x=175 x=35 (2x+7) ∘ =(2(35)+7) ∘ =77 ∘ (3x−2) ∘ =(3(35)−2) ∘ =103 ∘ And since the opposite angles of a parallelogram is equal, so, the angles will be 77 ∘ ,103 ∘ ,77 ∘ ,103 ∘ .

Answer:
The adjacent angles are given as (2x+7)

and (3x−2)
∘
.
Since, the sum of the adjacent angles of a parallelogram is 180
∘
, then,
2x+7+3x−2=180
5x+5=180
5x=175
x=35
(2x+7)
∘
=(2(35)+7)
∘
=77
∘
(3x−2)
∘
=(3(35)−2)
∘
=103

And since the opposite angles of a parallelogram is equal, so, the angles will be 77
