Answer:

Step-by-step explanation:

Using slope formula:

(y2-y1)/(x2-x1)

(-3 + 1) / (-2-2)

-2/-4

slope: 1/2

Point P is the incenter of triangle ABC, PZ = 7 units, and PA = 12 units.
cestrela7 [59]

The complete question is

"Point P is the incenter of triangle ABC, PZ = 7 units, and PA = 12 units.

The radius of the incircle centered at point P is ? units."

The radius of the incircle centered at point P is 7 units.

We are given that point P is the incenter of the triangle, and is the center point of the incircle of the triangle.

<h3>What is incircle?</h3>

The incircle is defined as the largest circle that can be made in a triangle and is tangent to each side of the triangle.

Here, The radius of the circle is going to be a perpendicular line from point P to any side of the triangle.

In the triangle ,

PZ = PY = PX,

Each measure of value is equal to the radius of the circle.

Therefore, we already know that PZ = 7 units making the radius, r = 7 units.

The length of the rectangular basketball court is 44 feet more than the width. If the perimeter of the basketball court is 288 f
Temka [501]
Let's first say that L=W+44

and then remember that perimeter is P=2L+2W

replace the L with W+44

we then get P=2(W+44)+2W, now I'll solve it

P=2W+88+2W
P=4W+88

substitute 288 for P

288=4W+88
200=4W
50=W

so now we now how wide the court is. add 44 to find the length which gives you L=94

as always plug the numbers back into your perimeter equation to ensure L and W are correct
