Answer 1

Hey there! here's your answer:

x= 30

Step-by-step explanation:

 

ABCD is a cyclic quadrilateral.

Opposite angles in a quadrilateral inscribed in a circle are supplementary.

hence,

∠ABC+∠ADC=180  

∠ABC=180  

−120   =60  

 

Also  ∠ACB=90  

( angle on a semi circle )  

In ΔABC we have  

∠BAC+∠ACB+∠ABC=180    (By angle sum property)

∠BAC+90  +60    =180

 ∠BAC=180  −150  

=30  

Hope I was able to help!!
