angle BAC= 55*
diameter of a circle subtend 90* angle on the circumference of the circle
therefore angle ACB =90
now
A+B+C= 180*. (angle sum prprty)
55*+90*+B=180*
145*+B=180*
B =180-145
B =35*
angle ABC =35*

angle BAC = 55°
angle BCA = 90°(angle in a semicircle if equal to 90°)
angle ABC = 180°-(55+90)°
=180°-145°
=35°

hello what is prprty
property was that sum of all the interior angle of a triangle is 180*
i mean that you've written prprty not property okay
so
