solve this question pleaseee

Answer 1

angle ABC = 55°.........

Answer 2

Given - angle CAB =35degree

To find - angle ABC
 
proof - we know that,

angle A+B+C = 180 degree

35+angle B+C= 180        (Angle A = 35degree)

we know that, in a circle chords are congruent and then the angles are equal

angleB+C = 180 - 35 

angle B+B = 145        (if two chords drawn in a circle then the chords are equidistance from circle )

2angle B = 145

angle B= 145/2
