Answer:

x = 44.4°

Step-by-step explanation:

Use SOHCAHTOA.

In this case, use sine trigonometric function formula

$\sin(x) = \frac{o}{h}$

The opposite side of angle is 7.

The hypoteneuse is 10.

So,

$\sin(x) = \frac{7}{10} \\ x = \sin ^{ - 1} ( \frac{7}{10} ) \\ x = {44.427}^{o} \\ x = {44.4}^{o}$

Answer:

44.4°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Sin = Opposite/Hypotenuse

sin(x) = 7/10

x = arcsin(7/10)

x = 44.4°

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 $36\degree$
