A young boy let’s out 30 feet of string on his kite. If the angle of elevation from the boy to his kite is 27”, how high is the

const2013 [10]

Answer:

The height of the kite from the ground is 13.617 feet

Step-by-step explanation:

Given as :

The measure of the string = 30 feet

The angle of elevation from the boy to his kite = 27°

Let the height of the kite from ground = H feet

So, From Triangle

Sin angle = $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$

Or, Sin 27° = $\dfrac{\textrm H}{\textrm 30}$

or, H = 30 × Sin 27°

I.e H = 30 × 0.4539

∴ H = 13.617 feet

Hence the height of the kite from the ground is 13.617 feet Answer

Solve for m y-y=m(x-x)

spin [16.1K]

Answer:

m = y/x

Step-by-step explanation:

y-y = m(x-x)

simplify:

-2y = m(-2x)

simplify again

-2y = -2mx

divide to get rid of -2 and x

-2y = -2mx

----------------

-2x

- = m

A rectangular garden has a length of (2y - 4) feet and a width of 4y^2 feet. How do you find the perimeter of the garden

Ber [7]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8 {y}^{2} + 4y - 8}}}}}$

Step-by-step explanation:

Given,

Length of a rectangular garden ( l ) = 2y - 4

Width of a rectangular garden ( w ) = 4y²

Perimeter of the garden = ?

Finding the perimeter of a rectangular garden having length of 2y-4 and width of 4y²

$\bold{ \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}}$

$\longrightarrow{ \sf2(2y - 4 + 4 {y}^{2}})$

Distribute 2 through the parentheses

$\longrightarrow{ \sf{4y - 8 + 8 {y}^{2} }}$

Arrange it in standard form

$\longrightarrow{ \sf{8 {y}^{2} + 4y - 8}}$

Hope I helped!

Best regards! :D

Two different sized triangles have a scale factor of 2:3. If the hypotenuse ( the longest side ) of the bigger triangle measures

OlgaM077 [116]

Answer:

16 in

Step-by-step explanation:

The 3 part of the ratio represents 24 inches.

Dividing by 3 gives the value of one part of the ratio.

24 in ÷ 3 = 8 in ← value of 1 part of the ratio, thus

2 parts = 2 × 8 in = 16 in ← hypotenuse of smaller triangle
