The roof leading to the top of a hill has an angle of elevation of 23 degrees. The hill is 120 feet high what is the leanth of t

Tresset [83]

Answer: $307.11\ ft$

Step-by-step explanation:

Given

The height of hill is 120 ft and the angle of elevation is $23^{\circ}$

Suppose the length of the road is $x$

From the figure, we can write

$\Rightarrow \sin 23^{\circ}=\dfrac{120}{x}\\\\\Rightarrow x=\dfrac{120}{\sin 23^{\circ}}\\\\\Rightarrow x=307.11\ ft$

Thus, the length of the road is $307.11\ ft$

Does anyone know the answer to this

algol [13]

Answer:

x² + (y+3)² = 4²

Step-by-step explanation:

A close look at the diagram reveals that the center of this circle is (0, -3) and that the radius is 4 units.

Starting from the general equation of a circle, (x - h)² + (y - k)² = r²

and substituting the givens (h = 0, k = -3, r = 4), we get:

x² + (y+3)² = 4². This is Answer B.

Find an equation, in slope-intercept form, that passes through the point (−4,3) with a slope of −3.

lisov135 [29]

Answer:

y = -3x - 9

Step-by-step explanation:

Equation of line in point slope form is given as:

$y - y_1 = m(x-x_1) \\y - 3= - 3\{x - (-4)\}\\y - 3 = - 3(x + 4)\\y =- 3x - 12 +3\\y = - 3x - 9\\ is \: the \: required \: equation \\$
