Question

plz find the value of x

Answer 1

x=43+52=95°.........

Answer 2

draw a PQ perpendicular to A and B through the point O.

consider POA,
angle P = 90
so, angle POA=180-(90+52)
=180-142
=38

consider QOB,
angle Q = 90
so, angle QOB=180-(90+43)
=180-133
=47

so, x= 180-(47+38) (linear pair)
=180-85
=95
