I'd say angle A = angle B
arc tangent (angle B) = 150 / 555
<span><span><span>arc tangent (angle B) = 0.2702702703 </span>
angle B = 15.124 degrees

By the way 555 feet is the height of the Washington Monument.

Which expressions are equivalent to this expression?
Lyrx [107]

Answer:

Option B

Option C

Option D

All of these are correct

Step-by-step explanation:

Option B is correct because:

2x + 1 + 2x + 3 = 4x + 4

=> 4x + 4 = 4x + 4

Option C is correct because:

x + 3x + 4 = 4x + 4

=> 4x + 4  = 4x + 4

Option D is correct because:

2(2x + 2) = 4x + 4

=> 4x + 4 = 4x + 4

Option A is incorrect because:

4(x + 4) = 4x + 4

=> 4x + 16 ≠ 4x + 4

Ying is a professional deep water free diver.
mash [69]

Answer:

The lowest point is -100 meters, or 100 meters down

Step-by-step explanation:

D(x)=1/36(x-60)^2-100

This equation is in vertex form

y = a(x-h)^2 +k  where (h,k) is the vertex

Since a is positive, the parabola opens up

The vertex is the minimum, which means it will be the lowest point

The vertex is (60,-100)

The lowest point is -100 meters, or 100 meters down

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters
