Answer:

height : 150 feet

Step-by-step explanation:

\sf \sf tan(x)= \dfrac{opposite}{adjacent}

using tan rule:

\hookrightarrow \sf tan(62)= \dfrac{b}{80}

\hookrightarrow \sf b = tan(62)*80

\hookrightarrow \sf b =150.46 \ feet

Answer:

\approx 150 \: ft

Step-by-step explanation:

recall sohcahtoa

  • sin(x)=opposite/hypotenuse
  • cos(x)=adjacent/hypotenuse
  • tan(x)=opposite/adjacent

here,

  • The adjacent side is 80 ft
  • x°=62°
  • The opposite side is the height

<u>To </u><u>find</u><u>:</u>

  • The opposite side or the height

since we are given the value of adjacent side and need to figure out the opposite side , we will work with tan function,

So,

\tan( {62}^{ \circ} )  =  \dfrac{h}{80}

\implies \: h = 80\tan( {62}^{ \circ} )

using calculator,we acquire

\implies \: h  \approx 150 \: ft

hence, the height of the building is approximately 150ft

The perimeter of the blueprint is represented by the equation P=8x. What is the equation of the perimeter when solved for x
Korvikt [17]

Answer:

x = P/8

Step-by-step explanation:

The perimeter of the blueprint is given by the equation :

P = 8x

We need to solve the above equation for x.

Dividing both sides of the equation by 8.

\dfrac{P}{8}=\dfrac{8x}{8}\\\\x=\dfrac{P}{8}

Hence, the value of x is P/8
