What is the 10th step in the given proof? statement: all three lines share point p. reason: definition of midpoint statement: two of the three medians share point p. reason: using point-slope formula statement: and are concurrent. reason: definition of concurrence statement: p lies on . reason: the coordinates of p satisfy the equation of . statement: point p lies on and . reason: from above algebra

As seen , what steps you have written  you just want to prove if in a triangle two medians have common point of intersection , a point P, then the third median will also pass through point P.

The point of intersection of medians is called Centroid.

The statement ahead of  :Statement: Point P lies on and .

Reason: from above algebra

Point P is the intersection of three medians which is  called Centroid of triangle.The Centroid divides the line from opposite vertex in the ratio of 2:1.

b

Step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
