In $\triangle ABC, \angle A = 68^\circ$. If is the incentre of the triangle, then measure of $\angle BIC$ is: |
124° 68° 148° 54° |
124° |
According to the concept, \(\angle\)BIC = 90 + \(\frac{1}{2}\) x \(\angle\)BAC = \(\angle\)BIC = 90 + \(\frac{1}{2}\) x 68 = \(\angle\)BIC = 90 + 34 = \(\angle\)BIC = \({124}^\circ\) Therefore, \(\angle\)BIC is \({124}^\circ\). |
