Answer:

x = 19, y = -5

Step-by-step explanation:

x + y = 14 => x= 14-y

2x + 4y = 18 => 2(x+2y)=18 => x+2y=9

x+2y=9 => (14 - y) + 2y = 9

14 + y = 9 => y = -5

x + (-5) = 14 => x=19

3. A utility pole is 38 ft tall. The pole creates a 53 ft shadow. What is the angle of elevation of the sun? Round your answer t

dybincka [34]

Answer:

The angle of elevation of the sun is $36\degree$ .

Step-by-step explanation:

Let $x$ be the angle of elevation of the sun as shown in the diagram.

Then the side length which is $38$ feet is opposite to $x$ and the side length which is $53$ feet is adjacent to $x$ .

Therefore we use the trigonometric ratio that involves the opposite and adjacent sides, which is the tangent ratio.

$\tan x=\frac{38}{53}$

$\Rightarrow \tan x=0.71698$

We solve for $x$ to get,

$x=\arctan (0.71698)$

$\Rightarrow x=35.63981$

To the nearest degree, the angle of elevation is $36\degree$
