<h3>Hello There!!</h3>

<u>Given</u>

\text{Length of the tree= 25 feet} \\  \text{Angle of Elevation= 30°}

<h3><u>To </u><u>Find</u></h3>

\text{Height Of The Tree}

\text{Let The Height of the Tree be ‘x’}

<u>We </u><u>Know</u><u>:</u><u>-</u>

\tan\theta =  \frac{ \text{perpendicular}}{ \text{base} }

\tan \theta =  \frac{ \text{height of the tree}}{ \text{length of the base}}  \\  \\  \implies  \tan30 =  \frac{ \text{x}}{25}  \\  \\  \implies  \text{x }= 25 \times  \tan30 \\  \\  \implies  \text{x }= 25 \times 0.577 \\  \\  \implies  \text{x} = 14.425 \\  \\  \implies \text{x} = 14.43

\therefore \text{height of the tree(\text{x})} =  \red{14.43 \:  \text{feet}}

Option C is the correct answer

<h3>Hope This Helps!!</h3>

What is the point-slope form of a line that has a slope of 5 and passes through the point (3, –4)?
Alinara [238K]

Answer:

y + 4 = 5(x - 3)

Step-by-step explanation:

In the Point-Slope Formula, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>all the negative symbols give the OPPOSITE terms of what they really are.

Can someone help me with these 2 questions please???
kodGreya [7K]

Answer:

See step-by-step explanation.

Step-by-step explanation:

For the first question, you simply put an EMPTY circle above 2 and draw an arrow from it all the way down to -3. The reason why we put an empty circle is because there is no equal sign below it.

For the second question, you put a FILLED circle above 4 and draw an arrow from it all the way down to -3. The reason why we use a filled circle is because x is less than OR equal to 4.

Answer:

22.3838476568 in²

Step-by-step explanation:

First you would find the area of sector (yellow). The formula is 75/360 x π x 3².

this is equal to 5.89048622548. Now the total circle area is 3²xπ = 28.2743338823. 28.2743338823 - 5.89048622548 = 22.3838476568 in²

Jefferson Middle School needs to see a 300% gain in PTO fundraiser
Ronch [10]

Given parameters:

Percentage gain = 300%

Selling cost last year = $2420

Unknown:

Selling cost this year  = ?

Solution:

To solve this problem;

     Profit percent  = \frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100

      300 = \frac{S - 2420}{2420}  x 100

      3 = \frac{S - 2420}{2420}

         S- 2420 = 7260

          S = $9680

To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
