SOLUTION
Draw the diagram
a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
Hence
SInce AC=30, Then
Thus, from the median properties of a triangle, AB = 15
Z and 113° are supplementary, they add to make up 180. So z + 113 = 180, z = 67°. x and 113° are equivelant, so 8x + 41 = 113, x = 9.
Remark
There are two formulas for doing this. I'll use the one that does not involve the slope. I think it will be easier for you to understand.
Step One
Decide which point is (x1,y1)
Since point P is 2/5 the way up from point A, we will call (x1,y1) point A
Step Two
Write the givens.
Point(A) = (-2,-3)
Point(B) = (3,2)
Step Three
Write the formula
x1 + ratio*(x2 - x1), y1 + ratio(y2 - y1)
Sub and solve.
-2 + 2/5 *(3 - - 2) , -3 + 2/5*(2 - -3)
-2 + 2/5(5) , - 3 + 2
-2 + 2 , - 1
P = (0 , - 1) <<<<<< Answer
