Nikolay [14]

The length of the ladder nearest hundredth of a foot is 23 feet.

We have given that,

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 20 feet up.

The ladder makes an angle of 77^{\circ}  the ground.

<h3>What is the sin ratio?</h3>

sin(\theta)=\frac{perpendicular \ side}{hypotenous}

Therefore we get,

\implies\frac{22}{H} =sin(77)

\implies H=22/sin(77)

\implies 22.59ft\\\\=23ft

Therefore, The length of the ladder nearest hundredth of a foot is 23 feet.

HELP!!
taurus [48]

Lets convert

  • 1mile=5280ft
  • 1h=3600s

\\ \rm\longmapsto 1mph

\\ \rm\longmapsto \dfrac{5280}{3600}ft/s

\\ \rm\longmapsto 1.46ft/s

If rounded

\\ \rm\longmapsto 1.5ft/s

katovenus [111]

Answer:

y = (ax)2

y = 2ax

divide both sides by 2a to make x the subject of the formula.

y/2a = 2ax/2a

x = y/ 2a

Please help me fast and show all your work please thx ​
laiz [17]

Answer:

area of trapezoid/trapezium = \frac{h}{2} *(a+b)

h=height

a and b are the parallel sides (top 2.5 and bottom 6 in this pic)

so \frac{5}{2} *(2.5+6) = \frac{5}{2}*(8.5) = \frac{42.5}{2}  = 21.25
