Answer
Find out the how high up the wall does the ladder reach .
To proof
let us assume that the height of the wall be x .
As given
A 25-foot long ladder is propped against a wall at an angle of 18° .
as shown in the diagram given below
By using the trignometric identity
![cos\theta = \frac{Base}{Hypotenuse}](https://tex.z-dn.net/?f=cos%5Ctheta%20%3D%20%5Cfrac%7BBase%7D%7BHypotenuse%7D)
now
Base = wall height = x
Hypotenuse = 25 foot
Put in the trignometric identity
![cos18^{\circ} = \frac{x}{25}](https://tex.z-dn.net/?f=cos18%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7Bx%7D%7B25%7D)
![cos18^{\circ} = \bar{0.9510565162}](https://tex.z-dn.net/?f=cos18%5E%7B%5Ccirc%7D%20%3D%20%5Cbar%7B0.9510565162%7D)
x = 23.8 foot ( approx)
Therefore the height of the ladder be 23.8 foot ( approx) .

Answer:
The angles are 26 and 64
Step-by-step explanation:
When two angles are complementary, what this means is that the add up to 90 degrees
Now, let’s say one of the angles is x, the other angle is 12 more than twice it; mathematically that would be 2x + 12
Since they add up to be 90, we have
x + 2x + 12 = 90
3x + 12 = 90
3x = 90-12
3x = 78
x = 78/3
x = 26
The other angle is 2x + 12 = 2(26) + 12 = 52 + 12 = 64
