A fireman learned a 36 foot ladder against a building.If he placed the ladder 7 feet from the base of the building,what angle is
andrew11 [14]
Answer:
The angle between the ladder and ground is 78.78°

Explanation:
It is given that the length of the ladder is 36 foot and the distance between the base and the ladder is 7 feet.

Here we can see that the hypotenuse is 36 foot and the base is 7 feet. To find the angle between the ladder and the ground we take the cos inverse of 7/36.

Let the angle between the ladder and the ground is ‘x’.

Please check the attached image, also report the answer above me for spamming and trying to receive free points as this has been an issue lately.

The length of the longer side of rectangle $r$ is $10$ percent more than the length of a side of square $s.$ the length of the s
liraira [26]
Let
x-------------> length of the side of a square

[area of a square]=x*x------> x²

[area of rectangle]=[shorter side]*[<span>longer side]
</span>[shorter side]=0.90 x-------> (<span>is 10% percent less than the length of a side of square)
</span>[longer side]=1.10x-------> (<span>is 10% percent more than the length of a side of square
</span>
[area of rectangle]=(1.10x)*(0.90x)-----> 0.99x²

[the ratio of the area of rectangle to the area of square]=0.99x²/x²=0.99

the answer is
the ratio of the area of rectangle to the area of square is 0.99
