Point p is the incenter of triangle rst. which must be true?

b

Step-by-step explanation:

Midline

The correct option is 2.

Step-by-step explanation:

Incenter of a triangle is the intersection point of all bisectors. The length of the perpendiculars form the incenter to all sides, are equal.

According to the given information P is incenter of the triangle.

The lines PA,PB,PC are perpendicular form the incenter to the all sides. So if we draw a circle insides the triangle with center P and radius PA, then PB and PC represent the radius of the circle.

Since these line segments are equal therefore we can say that

Option 2 is correct.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
