Answer:
K(-4,8) is the ortho center.
Step-by-step explanation:
In a right angled triangle, The vertex of the right angle is the ortho center.
Here we are given
J(-4,-1), K(-4,8) & L(2,8)
Using distance formula we get



So we can say that

By converse of pythagorean theorem we get

Hence the Vertex of the right angle is K(-4,8)
K(-4,8) is the ortho center.
DCA is 116 because x=29, when you plug 29 into x you get 116
The second and the third one are similar.
Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean =
=
= 17
Noe find the mean of 25 and 17 and 17 and 9
mean =
=
= 21 and
mean =
=
= 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
