$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

In the cyclic quadrilateral ABCD

∠ABC = 180° - 120° = 60°

∠BCA = 90°

Therefore:

x = ∠BAC = 180°- (90° + 60°) = 30°

• Hence, the value of x is 30°.

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Answer 2

Answer:

In trapezium ABCD

D=B

so,B=120°

and also A=C

so,(120°+120°+A°+C°)=360°

240+2A=360

2A=360-240=120°

A=120/2=60°

therefore,x=60/2=30°
