Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
( substitute in values )
=
( cross- multiply )
12(x - 1) = 72 ( divide both sides by 12 )
x - 1 = 6 ( add 1 to both sides )
x = 7

The parallel line segment SV is half of RW
that is x = 7.5
SV also divides the sides RT and WT in proportion, that is
=
( cross- multiply )
10y = 24 ( divide both sides by 10 )
y = 2.4
Answer:
First equation is -425
Second equation is 11.25
Step-by-step explanation:
First equation we can write as
computing
When i=0 ->
When i=1 ->
...
When i=7 ->
then replacing each term we have
For the second equation we'll have 9 terms, solving in a similar fashion
When i=1 ->
When i=2 ->
When i=3 ->
...
When i=9 ->
So we have 0.25 + 0.50 + 0.75 + 1.00 + 1.25 + 1.50+ 1.75 +2.00 +2.25
