<h3>
<u>Given</u><u>:</u><u>-</u></h3>
Area of a square game board = 179 inches ²
<h3>
<u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u><u>-</u></h3>
Calculate the side of given square game board.
<h3 /><h3>
<u>Formula</u><u> </u><u>applied</u><u>:</u><u>-</u></h3>
Area of square = ( Side )²
<h3>
<u>Solution</u><u>:</u><u>-</u></h3>
We know that,
Area of square = ( Side )²
★ Substituting the value in the above formula, we get :
=> 179 = ( Side )²
=> Side = √179
=> Side = 13.37 inches ( approx )
Assume the number 100. 100*1.09=109. You then do 109*0.86=93.74.
So the overall decrease is 6.26%.
I think it’s the third one hope this helps
Given :
An airplane flying at an altitude of 2600 m is approaching an airport run away located 56 km away.
To Find :
The airplane’s angle of decent.
Solution :
Height of plane, h = 2600 m.
Horizontal distance of airplane from vertices is, d = 56 km = 56000 m.
Let, angle of depression is Ф.
So,

Therefore, the angle of decent is 87.34°.
Hence, this is the required solution.
