Question

solve this example please

Answer 1

In a trapezium,

opposite angles are supplementary.

therefore,

<ADB + <ABC = 180

<ABC = 180 - 120

<ABC = 60…

now,

since angle of semicircle is 90,

therefore,

<ACB = 90…

therefore,

by angle sum property,

X = 30//

Answer 2

i am not sure but se answer by thecangle sum is=30//
