Grayson is flying a kite, holding his hands a distance of 2.75 feet above the ground and letting all the kite’s string play out.
sergiy2304 [10]

The position of the kite with the point directly beneath the kite at the same

level with the hand and the hand for a right triangle.

  • The height of the kite above the is approximately <u>66.314 feet</u>.

Reasons:

The height of his hands above the ground, h = 2.75 feet

Angle of elevation of the string (above the horizontal), θ = 26°

Length of the string, <em>l</em> = 145 feet

Required:

The height of the kite above the ground.

Solution:

The height of the kite above the ground is given by trigonometric ratios as follows;

\displaystyle Height \ of \ kite, \, k_h = \mathbf{h + l \times sin(\theta)}

Therefore;

\displaystyle Height \ of \ kite, \, k_h = 2.75 + 145 \times sin(26^{\circ}) \approx \mathbf{66.314}

The height of the kite above the, k_h ≈ <u>66.314 feet</u>

Helene bought 6 bottles of juice. The bottles were on sale at 10 bottles for $12. Which explanation correctly tells how to calcu
Makovka662 [10]
<span>she wanted to buy 6 bottles.
the cost of 10 bottles was $12.
therefore we need to find the cost of one bottle and then find the cost for 6 bottles.                                           
if 10 bottles cost - $ 12                                                                                  
then 1 bottle costs - $ 12 / 10 bottles
                                         
here we divided 12 by 10 , cost of 1 bottle is 12/10 to find the cost of 6 bottles we have to multiply by 6 .12 / 10 x 6
                                                                                 
correct answer is therefore B. divide 12 by 10 and then mulitply by 6</span>

Olin [163]

Step-by-step explanation:

<em>Here </em><em>we </em><em>can </em><em>see </em><em>it </em><em>is </em><em>an </em><em>isosceles </em><em>triangle </em><em>so </em><em>base </em><em>angles </em><em>are </em><em>equal </em>

<em>x </em><em>+</em><em> </em><em>x </em><em>+</em><em> </em><em>8</em><em>0</em><em>°</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em><em><</em><em>Being </em><em>sum </em><em>of </em><em>angles </em><em>of </em><em>triangle </em><em>></em>

<em>2x </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em><em> </em><em>-</em><em> </em><em>8</em><em>0</em><em>°</em>

<em>2x </em><em>=</em><em> </em><em>1</em><em>0</em><em>0</em><em>°</em>
