Answer:

y=x-2.5

Step-by-step explanation:

If it is perpendicular to a, just like b, it has the same slope, but, it has a y-intercept of 2.5, unlike b, which has a y-intercept of 1

iVinArrow [24]

Diameter D of the trampoline = 17 feet

The circumference C, of the trampoline is calculated by the formula:

$C=\pi D$

Put D = 17 feet, π=3.14

$\begin{gathered} C=3.14\times17\text{feet} \\ C=53.38\text{feet} \end{gathered}$

I'll give more points here is what I need.

Serga [27]

Answer:

The answer to your question is x = 3; y = 3

Step-by-step explanation:

Data

angle = 45°

Opposite side = x

Adjacent side = y

hypotenuse = 3√2

To solve this problem, use trigonometric functions.

1) To find x, use the trigonometric function sine.

sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

Opposite side = hypotenuse x sin Ф

-Substitution

Opposite side = 3√2 sin 45

-Simplification

Opposite side = 3√2 (1 / √2)

Opposite side = 3(1)

-Result

x = 3

2) To find y use the trigonometric function cosine

cos Ф = Adjacent side / hypotenuse

-Solve for Adjacent side

Adjacent side = hypotenuse x cos Ф

-Substitution

Adjacent side = 3√2 x cos 45

-Simplification

Adjacent side = 3√2 x (1/√2)

Adjacent side = 3(1)

-Result

y = 3

Ms.Henderson is using triangles in her graphic design project.The triangles are isosceles.One had a base of 4 inches and legs of

tester [92]

If the two triangles are similar you can use a proportion to solve for the length of the legs.
$\frac{2}{4}$ = $\frac{x}{9}$
Now, you would cross multiply to get
4x=18
Now, you simplify that using the division property of equality.
You end up with
x=4.5
Therefore, the legs of the triangle with a base of 9 inches will each be 4.5 units long.
