Answer:

New\ Position = -415m

Step-by-step explanation:

Given

Position= -300m

Descend = 115m

Required

Determine the new position

It descends means that it moved in the downward position.

So, the new position is:

New\ Position = Position - Descend

New\ Position = -300m - 115m

New\ Position = -415m

<em>Hence, the new position f the submarin is -415m</em>

A ladder is leaning against a tall wall with the foot of the ladder placed at 7 feet from the base of the wall and the angle of
djverab [1.8K]

Complete question is;

A 21 ft ladder is leaning against a tall wall with the foot of the ladder placed at 7 feet from the base of the wall and the angle of elevation is?

Answer:

θ = 70.5°

Step-by-step explanation:

The angle of elevation simply means the angle that the ladder makes with the ground. Let's call this angle θ.

I've attached a diagram showing the triangle made by this ladder and the wall.

From the attached diagram, we can see the triangle formed by the ladder and the wall.

We can find the angle of elevation θ from trigonometric ratios.

Thus;

7/21 = cos θ

cos θ = 0.3333

θ = cos^(-1) 0.3333

θ = 70.5°

The 3 angles form the straight line AB. A straight line equals 180 degrees.

The 3 angles when added together need to equal 180:

2x + 65 + (x + 65) = 180

Simplify by combining like terms:

3x + 130 = 180

Subtract 130 from both sides

3x = 50

Divide both sides by 3

X = 50/3

X = 16 2/3 (16.66667 as a repeating decimal)

Now you have x if you need to solve all the angles replace x with its value and sole:

2x = 2(16 2/3) = 33 1/3

X + 65 = 16 2/3 + 65 = 81 2/3

Answer:

4x + 8y = 50 or 4x + 8y > 50

Step-by-step explanation:

To find which equation show the exact answer, Becasue he need at least 50 poitns to have a B, so:

4x + 8y must larger or equal to 50

In these choice, some I can't figure out what it means but the correct answer for this is:

4x + 8y = 50 or 4x + 8y > 50

Hope this help you :3

What is the measure of an interior angle of a regular three-sided polygon?
noname [10]
The formula to find the measure of an interior angle is (n - 2) * 180/n, where n represents the number of sides in the polygon. In this problem, n would represent 3. 

Let's plug in the value for n
(3 - 2) * 180/3
Let's simplify that. 
=60

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!
