Complete Question

A twelve-foot ladder is leaning against a wall. If the ladder reaches eight ft high on the wall, what is the angle the ladder forms with the ground to the nearest degree?*

Answer:

42°

Step-by-step explanation:

From the question, the diagram that is formed is a right angle triangle.

To solve for this, we would be using the trigonometric function of Sine.

sin θ = Opposite side/ Hypotenuse

From the question, we are told that:

12 foot ladder is leaning against a wall = Hypotenuse

The ladder reaches 8ft high on the wall = Opposite side.

Hence,

sin θ = 8ft/12ft

θ = arc sin (8ft/12ft)

= 41.810314896

Approximately to the nearest degree

θ = 42°

Therefore, the angle the ladder forms with the ground to the nearest degree is 42°

Please help!!! Please hellp me i do not know the answr to this question.

Alchen [17]

Answer:

77.7

Step-by-step explanation:

First all the angles add up to 360°. You would subtract 180 from the 360 because of the 2 right angles. That leaves you with 180. Then 180-102.3 to get 77.7°, your answer.

Find the slope of the line that passes through (87, 91) and (88, -4).

Elanso [62]

<h2>Answer: slope = - 95</h2><h2> </h2>

Step-by-step explanation:

The question gives us two points, (87, 91) and (88, -4), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)

= (91 - (- 4)) ÷ (87 - 88)

= - 95

Checking my answer:

Finding the Equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

⇒ y - (-4) = - 95 (x - 88)

y + 4 = - 95 (x - 88)

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.

Bikes'R'Us manufactures bikes, which sell for $250. It costs the $180 per bike, plus a startup fee of $3,500. After how many bik

lions [1.4K]

Answer:

The bikes sold at break even by the manufacturer is 50 units

Explanation:

We know that break even point is given by the following formula,

$\frac{\text { Fixed costs }}{\text { (Price per unit - Variable costs) }}$

We are given startup fee = $3500 which is the fixed cost,

the bikes sell for $250 which is the price per unit and

cost per bike is equal to $180

So substituting these values in the formula we get

= $\frac{3500}{(250-180)}$

= $\frac{3500}{(70)}$ = 50

= 50 units which is the number of bikes sold at break even by the manufacturer.
