Mathematics

postnew [5]3 years ago
4 0

the triangle formed by sides 10, 9 and 15 units can't be a right angled triangle, because they doesn't form the pythagorean triplet, that is the sum of squares of the smaller sides isn't equal to the square of largest side,

sum of squares of smaller sides

=》

10 {}^{2}  + 9 {}^{2}

=》

100 + 81

=》

181

now, square of largest side (hypotenuse)

=》

{15}^{2}

=》

225

they aren't equal, proved

(x−7)2−25=0<br><br> smaller x =<br> larger x =
nexus9112 [7]

Remark

Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.

Solution

(x - 7)^2 - 25 = 0                 Add 25 to both sides

(x - 7)^2 - 25 + 25 = 25      Combine the left

(x - 7)^2 = 25                       Take the square root of both sides.

sqrt(x - 7)^2 = sqrt(25)

x - 7 = +/-   5                        Add 7 to both sides

x = 7 +/- 5

=========

x1 = 7 + 5

x1 = 12

x2 = 7 - 5

x2 = 2

Smallest x = 2

Largest x = 12

An airplane pilot can see the top of a traffic control tower at a 20 degree angle of depression. the airplane is 5,000 feet away
daser333 [38]

The given question describes a right triangle with with one of the angles as 20 degrees and the side adjacent to the angle 20 degrees is of length 5,000 feet. We are looking for the length of the side opposite the angle 20 degrees.

Let the required length be x, then

\tan{20^o}=\cfrac{opp}{hyp}=\cfrac{x}{5,000}\\ \\ \Rightarrow x=5,000\tan{20^o}=1,819.85

Therefore, the height of the airplane above the tower is 1,819.85 feet.
