Use the slanted height of 20ft

Nataly [62]3 years ago

Answer:

Step-by-step explanation:

We can use the Pythagorean theorem to find the height

a^2 + b^2 = c^2 with a and b legs and c the hypotenuse

The triangle is a right triangle with legs GH and FG and hypotenuse FH

FG^2 + GH^2 = FH^2

FG ^2 + 12^2 = 20^2

FG^2 +144 = 400

Subtract 144 from each side

FG^2 +144-144 = 400-144

FG^2 =256

Take the square root of each side

sqrt(FG^2) =sqrt(256)

FG = 16

NEED HELP PLEASE!!! Given f(x)=9x+4 and g(x)= -5x+1, what is g(x)-f(x)?

GenaCL600 [577]

Answer:

g(x) - f(x) = -14x - 3

Step-by-step explanation:

We need to subtract the function f(x) = 9x + 4 from the function g(x) = -5 + 1. Rewriting these two functions in columns, we get

g(x)= -5x+1

- f(x) = -(9x+4) Note: Use parentheses as shown here.

--------------------

g(x) - f(x) = -14x - 3

Use the point and the slope to graph each line. Write the equation of the line. The line passes through point (2,-2) and is para

elixir [45]

Answer:

y= -x

Step-by-step explanation:

slope- intercept form

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -1, m= -1.

Substitute m= -1 into the equation:

y= -x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= 2, y= -2,

-2= -2 +c

c= -2 +2

c= 0

Thus, the equation of the line is y= -x.

Ms. Mwanted to estimate the height of the Republic Plaza building in downtown Denver. She has an app on

Volgvan

Answer:

The height of the bullding is 717 ft

Step-by-step explanation:

Right Triangles

The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.

The tangent ratio for an internal angle A is:

$\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}$

The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.

The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:

$\displaystyle \tan 82^\circ=\frac{h}{100}$
