Question

triangle ABC=90 and triangle ACB =70 find the triangle AIC​

Answer 1

Answer:

ABC is a triangle whose incentre is I. <ABC=90, <ACB = 70. Therefore, <BAC= 180–90–70 = 20. AI, BI and CI are angle bisectors. So in triangle AIC, <IAC = 20/2 = 10 and <ICA = 70/2 = 35 Hence <AIC = 180–10–35= 135 deg.

Answer 2

Answer:

By Angle sum property

90+70+x= 180

x= 180-160

x=20
