A circle has its center at (2,-4). The radius of the circle extends to the

m_a_m_a [10]

Check the picture below, so the circle looks more or less like so, with a radius of 9.

$\textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=9 \end{cases}\implies C=2\pi (9)\implies C\approx 57$

joja [24]

Answer:

Angle of elevation = 80°

Step-by-step explanation:

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?

To solve for angle of elevation, we use the Trigonometric function of Tangent.

tan θ = Opposite side/Adjacent side

Opposite side = Height of the tower = 217 ft

Adjacent side = 38ft

tan θ = 217/38

tan θ = 5.6315789474

θ = arc tan 5.6315789474

= 79.930937301°

Approximately = 80°

A wheelchair ramp is 8.0 m long. The angle of inclination is 10°. Calculate the rise of

garik1379 [7]

Answer:

The height of the ramp is 1.39 m.

Step-by-step explanation:

We have,

A wheelchair ramp is 8.0 m long

The angle of inclination is 10°

It is required to find the rise of the ramp.

Here, hypotenuse is 8 m and angle of inclination is 10°.

Using trigonometry to find it.

$\sin\theta=\dfrac{x}{8}$

x is rise of the ramp

$x=\sin(8)\times 10\\\\x=1.39\ m$

So, the height of the ramp is 1.39 m.
