Question

Find the value of x if the opposite angles of a parallelogram are 2x⁰ and (3x-40)​

Answer 1

Answer:

We know that,

• Opposite angles of a parallelogram are same

Therefore,

$2x = 3x - 40 \\ \\ = > 2x - 3x = - 40 \\ \\ = = > - 1x = - 40 \\ \\ = = = > 1x = 40 \\ \\ = = = = > x = \frac{40}{1} \\ \\ = = = = = > x = 40</strong><strong>°</strong><strong>$

:. x = 40°

Answer 2

Explanation:

"The opposite angles of a parallelogram are equal"

So ,

• 2x = 3x - 40
• 2x - 3x = -40
• -1x = -40
• Cancel minus ["-"] on both sides
• 1x = 40
• x = 40/1
• x = 40°
