Question

If I is the incentre of ∆XYZ, IYZ = 30° AND IZY = 40° , find YXZ. ​

Answer 1

Answer:

40°

Step-by-step explanation:

In Centre is the point of concurrence of all 3 angle bisectors of a triangle.

If <iyz =30° triangle angle is 60°(because angle bisector divides it)

If <izy =40°triangle's angle is 80°(because angle bisector divides it)

Triangle's total angle=60+80=140°

<yxz=180-140=40°
