Answer:

The answer is 14.

Step-by-step explanation:

Since all of the angles of a triangle add up to be 180, then all you have to do is add the 2 angles together that you have and subtract that number from 180. For example 141+25=166, so, 180-166=14. 14 would be the measure of the third angle.

HELLP!! PART C How does each conic surface inside the telescope affect the path of light?

Paraphin [41]

Explanation:

The point of a reflecting telescope is to reflect the light toward the eyepiece. That's what each reflecting surface does. By arranging the locations of the foci in the manner described, the light path is made to go from one focus to another, and finally to the focus at the eyepiece location.

Each conic surface is a reflecting surface that reflects the light closer to the eyepiece.

Given the graph of m(x), find m(-2). A.-2 B.0 C.5 D.-10

vesna_86 [32]

It would be 5. -2 is the input of the function, do you just have to find the y point / output of the function at x=-2, which is 5.

A greenhouse room at a botanical Garden is in the Shape of a hemisphere. The height at the center of the dome is 24 feet what is

DaniilM [7]

Answer:

The volume is $9,216\pi\ ft^{3}$

Step-by-step explanation:

we know that

The volume of the hemisphere ( a greenhouse room) is equal to

$V=\frac{4}{6}\pi r^{3}$

In this problem we have

$r=24\ ft$

substitute

$V=\frac{4}{6}\pi (24)^{3}=9,216\pi\ ft^{3}$

Built in 2011, the capital gate tower is 150 meters tall (measured vertically from the ground) and makes a 72 degree angle with

Softa [21]

Answer:

Step-by-step explanation:

You can create a right triangle out of this information and then use right triangle trig to solve.

We are given the height of the triangle as the height of the tower which is 150m.

We are given the angle of inclination as the degree the tower makes with the ground which is 72.

From the angle of 72 degrees, which is also known as the reference angle, we have the side across from it (the height) and we are looking for the side adjacent to it (how far from the base of the tower the keys will land). Side opposite the reference angle over side adjacent to the reference angle is the tangent ratio:

$tan(72)=\frac{150}{x}$ and, solving for x,

$x=\frac{150}{tan(72)}$

Make sure your calculator is in degree mode to solve this. Divide 150 by the tan(72) and find that

x = 48.7 m
