Question

If two opposite angles of a parallelogram are (5x - 5)° and (4x + 5 )°,then value of x is
​

Answer 1

☯︎ ᴀɴsᴡᴇʀ

we have,

• two opposite angles of a parallelogram are

• (5x - 5)°
• (4x + 5)°

and we know that,

★ opposite angles of a parallelogram are equal

➪ 5x - 5 = 4x + 5

➪ 5x - 4x = 5 + 5

➪ x = 10

therefore, value of x is 10
