Opposite angles of a rhombus are (2x) ° and (3x - 40) ° .Find value of x.​

Answer»

ANSWER:

X=40°

EXPLANATION:

As we know that Opposite Angles in a RHOMBUS are always equal and adjacent angles are sum of 180°. Here in this question we have given two Opposite Angles of a rhombus to be (2x)° and (3x-40)° and we have to FIND the VALUE of x.

So let's start!

(2x)°=(3x-40)°   [∵ Opposite Angles of rhombus]

⇒  2x=3x-40°

⇒  40°=3x-2x

⇒  40°=x

Hence the required value of x is 40°.
