The exact value of the y in the similar right triangle is 2.2360679775 units
The triangles are similar.
Similar triangles have corresponding sides of equal ratio.
The corresponding angles of similar triangle are equal.
Therefore, using similar ratio,
y / 5 = 1 / y
cross multiply
y × y = 5 × 1
y² = 5
square root both sides
y = √5
Therefore,
y = 2.2360679775 units

Answer:
Step-by-step explanation:
Givens
Observe the small triangle at the right. The smallest side is one.
The hypotenuse is y
In the largest tringle, the hypotenuse is 5
The smallest side is y
You can set up a ratio for this situation
Equation
smallest side - smallest triangle Largrest triangel -- largest side
============================ =========================
hypotenuse - smallest triangle hypotenuse -- largest triangle
1/y = y / 5 Cross Multiply
Solution
y^2 = 1*5 Take the square root of both sides.
√y^2 = √5
or
y =

The series 1/5, 2/15, 4/45, 8/135... converges and sums up to 3/5
Consider the infinite geometric series
1/5, 2/15, 4/45, 8/135...
With first term, a=1/5
common ratio, r = ⅔
The series converge because the common ratio, |r|<1.
The sum to infinity of a geometric series, S= a/(1-r)
S= 1/5 ÷ (1-⅔) = 1/5 ÷ 1/3 = 3/5
Therefore, the geometric series 1/5, 2/15, 4/45, 8/135... sums up to 3/5.
