In ΔABC, ∠A = 68°. If I is the incentre of the triangle, then the measure of ∠BIC is: |
124° 112° 68° 56° |
124° |
According to the concept \(\angle\)BIC = \({90}^\circ\) + \(\frac{1}{2}\) x \(\angle\)BAC \(\angle\)BIC = \({90}^\circ\) + \(\frac{1}{2}\) x \({68}^\circ\) \(\angle\)BIC = \({90}^\circ\) + \({34}^\circ\) \(\angle\)BIC = \({124}^\circ\) Therefore, \(\angle\)BIC is \({124}^\circ\) |
