Which of the following steps is needed to inscribe a circle in a triangle? O Find the incenter of the triangle
O Find the circumcenter of the triangle
O Find the orthocenter of the triangle
O Find the centroid of the triangle

the correct option is;

Find the incenter of the triangle

Step-by-step explanation:

To inscribe a circle in a triangle, we proceed as follows;

1) With the compass, draw the angle bisector of an interior angle of the triangle

2) Construct the angle bisector of a second interior angle of the triangle

3) From the point of intersection of the two angle bisectors which is the incenter of the triangle construct a line perpendicular to one of the sides of the triangle

4) With the compass at the incenter, extend the length to the point of intersection of the perpendicular line and the side of the triangle, then draw the inscribed circle of the triangle.

Therefore, the correct option is to find the incenter of the triangle.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
