Answer 2

angel A + angel B + angel C=180°

70°+angel B + angel C =180°

angel B + angel C =180°-70°

angel B + angel C=180°

angel BIC + angel CBI + angel IBC =180°

angel BIC + 1\2( angel ABC)+ 1\2(angel ACB)=180°

therefore, angel BIC + (angel ABC + angel ACB)=180°

therefore, angel BIC + 1\2(110°)=180°

angel BIC+55=180°

angel BIC=180°-55°

angel BIC=125°
