Question

In the figure below, find the exact value of y. (Do not approximate your answer.)

Answer 1

The exact value of the y in the similar right triangle is 2.2360679775 units

How to find the side of a triangle?

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 2

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

y = √5

or

y =
