Question

(C) In the given figure, ABCD is a mombus
Find the value of x​

Answer 1

suppose middle point is O

In this there are four triangles (triangle AOD, triangle DOC, triangle BOC, triangle AOC)

We know that a triangle has 180 degree

C=36degree

O=90degree

X=C+O+B=180degree

36+90+B=180 degree

B=180-30+90degree

=180-126 degree

=54 degree

X =54degree
