• Trey attended a New Year's Eve event and watched a ball drop at midnight. Prior
jekas [21]

Answer:

x=60.9°

Step-by-step explanation:

Given that the height of ball from the ground is 150ft

The base of the pole with the ball is 80 ft from where Trey is standing

Trey's horizontal line of sight is 6 feet above ground, then;

The height of ball from Trey's horizontal line of sight is;

150ft-6ft = 144ft

To find the angle x, assume a triangle with a base of 80 ft , a height of 144 ft and a slant height that represent the line of sight at an angle x

To get angle x , you apply the tangent of an angle formula where;

tan Ф°= length of opposite site of the angle/length of the adjacent side of the angle

tan x°= 144/80

tan x°=  1.8

x°= tan⁻(1.8)

x°=60.9°

How do you do this problem 1/4 +4x/5=11/20?
Nutka1998 [239]
\frac{1}{4}+\frac{4}{5}x=\frac{11}{20}\\\\\frac{4}{5}x=\frac{11}{20}-\frac{1}{4}\\\\\frac{4}{5}x=\frac{11}{20}-\frac{5}{20}\\\\\frac{4}{5}x=\frac{6}{20}\ \ \ \ \ \ \ |\cdot\frac{5}{4}\\\\x=\frac{30}{80}=\frac{3}{8}

Solve for U <br><br> 11=8+u/7.68
BlackZzzverrR [31]

\begin{gathered}\\ \sf\longmapsto 11=\frac{8+u}{7.68}\end{gathered}

\begin{gathered}\\ \sf\longmapsto 11 =  \frac{8 + u}{ \frac{192}{25} } \end{gathered}

\begin{gathered}\\ \sf\longmapsto 11=\frac{(8+u)×25}{192}\end{gathered}

\begin{gathered}\\ \sf\longmapsto 11=\frac{200+25u}{192}\end{gathered}

\begin{gathered}\\ \sf\longmapsto 2112=200+25u\end{gathered}

\begin{gathered}\\ \sf\longmapsto 2112-25u=200\end{gathered}

\begin{gathered}\\ \sf\longmapsto -25u=200-2112\end{gathered}

\begin{gathered}\\ \sf\longmapsto -25u=-1912\end{gathered}

\begin{gathered}\\ \sf\longmapsto u=\frac{1912}{25}\end{gathered}

<u>Alternate form:</u>

<u>u</u><u>=</u><u>76.48</u>

Michelle is making throw pillows to decorate her couch. She is going to make two square pillows that are each 2 feet by 2 feet a
lesantik [10]

ok so for the 2 ft pillows the perimeter would be 8 ft and for the 1 ft pillows the perimeter would be 3 ft. So you would need 8(2)+3(3)=16+9=25 so she needs 25 feet of trimming.
