Answer 1

Step-by-step explanation:

quad. ABCD is a cyclic quadrilateral.

( cylic quadrilateral is the quadrilateral which us enclosed in a circle)

opposite angles of cyclic quadrilateral are supplentry i.e their sum is equal to 180°

In triangle ABC,

angle BAC is given 20°

angle ACB = 90°

( Angle in a semi circle is 90°)

Therefore, angle ABC = 180-(90°+20°)

= 180°-110° = 70°

Now, ABCD is a cyclic quadrilateral

angle B + angle D = 180°

70° + x = 180°

x = 180° - 70°

x = 110°
