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}

now

\theta = 18^{\circ}

Base = wall height = x

Hypotenuse = 25 foot

Put in the trignometric identity

cos18^{\circ} = \frac{x}{25}

cos18^{\circ} = \bar{0.9510565162}

x = 23.8 foot ( approx)

Therefore the height of the  ladder be 23.8 foot ( approx) .

Given the equation y=1/3x+4 , what is the value of y if x = 3? State your answer in decimal form.
Sonja [21]
Y=5. if you do the problem you would plug in 3 for x, so the equation would be y=1/3(3)+4. 1/3 times 3 equals 1, so then it would be 1 plus 4 which equals 5. therefore, y=5.

hope this helps:)
