Similar triangles have their corresponding sides in the same ratio. So we have

x/8 = 9/5

cross multiply
5*x = 8 * 9

5x = 72

now divide both sides by 5:-

x = 72/5 = 14.4   Answer

Find endpoint with given endpoint and midpoint
TEA [102]

Answer:

(21, 17 )

Step-by-step explanation:

Using the midpoint formula and equating to the coordinates of the midpoint.

Let endpoint 2 have coordinates (x, y ), then

0.5(x - 3) = 9 ( multiply both sides by 2 )

x - 3 = 18 ( add 3 to both sides )

x = 21

and

0.5(y - 5) = 6 ( multiply both sides by 2 )

y - 5 = 12 ( add 5 to both sides )

y = 17

endpoint 2 = (21, 17 )
