Help please!! Solve for y.
Nimfa-mama [501]

Answer:

y = 3\sqrt{7}

Step-by-step explanation:

The 2 right triangles inside the right triangle are similar, then ratios of corresponding sides are equal, that is

\frac{y}{9} = \frac{7}{y} ( cross- multiply )

y² = 63 ( take the square root of both sides )

y = \sqrt{63} = 3\sqrt{7}

a tree 20 feet tall with a circumference of 3 ft has a vine wound around 7 times. How long is the vine?
FinnZ [79.3K]

If the tree is 20 feet tall with circumference 3 feet then the length of  vince is around 21 feet.

Given the height of tree is 20 feet and the circumference of tree is 3 feet.

We have to find the length of vine.

Circumference is the perimeter of a circular object. Because the trunk of a tree is in shape of circle so the perimeter of the trunk is 2πr.

We have been given the circumference of tree be 3 feet.

Circumference=2πr

Because vine is 7 times the circumference so the length of vine being:

Length of vine=7*3

=21 feet.

Hence if the tree is 20 feet tall with circumference 3 feet then the vince is around 21 feet long.

CAN SOMEONE PLEASE HELP ME WITH MY MATH ASAP PLEASE!!!!​
densk [106]

Answer:

5

Step-by-step explanation:

The height of the largest triangle = √(9 * 25) = 3 * 5 = 15

y is the square root of (25^2 + 15^2)

y = √(625 + 225)

y = √850

y = √(2 * 5*5 * 17)

y = 5 * √34

5 goes in the box.
