Answer:

In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12

In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x

Step-by-step explanation:

3x^2 -23x + 40 = (3x - 8) (x - 5)

3x^2 -17x + 24 = (3x -8) ( x - 3)

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 $36\degree$
