Answer 1

Answer:

we know that, 140°+angle A+angle C=180°

=angle A +angle C=180°-140°

=angle A + angle C =40°

And angle x is the external angle of ∆ABC

so, angle X = angle A +angle C

angle X =40°

hence the answer

Answer 2

We know that sum of opposite angles in a cyclic quadrilateral is 180°

∠ADC + ∠ABC = 180°

=>∠ABC= 180°-140°= 40°

=>∠ABC= 40°

since ∠ACB is an angle in a semi circle so

∠ACB = 90°

In ∆ABC,

∠ABC+∠CAB+∠ACB=180°

=> 40°+X°+90°=180°

=> 130°+X° = 180°

=> X°= 180°-130° = 50°

Therefore Value of X = 50°
