Question

8. In the given figure, ABCD is a rhombus. What
is the value of y-X?​

Answer 1

Answer:

In the above figure AOB= 40°

AOB=OCD=40°

We know ,

the two diagonals of a rhombus bisect at 90°.

therefore y=90°

In triangle OCD the angles are 40° and 90° .

therefore,

x+40°+90°=180°(as summation of all internal angles of a triangle is 180°)

or, x=180°-130°=50

x=50° and. y=90°
