Answer:

5.18 feet

Step-by-step explanation:  

We have been given that a ladder that is 20 feet long is leaning against the side of a building if the angle formed between the ladder and the ground is 75 degrees.

We can see from the attachment that side with 20 feet is hypotenuse and side x is adjacent side to the angle 75 degrees.

\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}

Substitute the given values:

\text{cos}(75^{\circ})=\frac{x}{20}

\frac{x}{20}=\text{cos}(75^{\circ})

\frac{x}{20}*20=20*\text{cos}(75^{\circ})

x=20*0.258819045103

x=5.1763809

x\approx 5.18

Therefore, the bottom of the ladder is 5.18 feet away from the base of the building​.

The standard form of a quadratic equation is ,

ax² + bx + c = 0.

And the formula to find the discriminant is b² - 4ac.

Here the first step is to change the given equation into standard form. So, add 1 to each sides of the equation. Therefore,

2x² – 9x + 2+1 = –1 + 1

2x² – 9x + 3 = 0

Next step is to compare the given equation with this equation to get the value of a, b and c.

After comparing the equations we will get a = 2, b = -9 and c = 3.

So, discriminant = b²- 4ac

=( -9)²-4 (2)(3)

= 81 - 24

= 57

So, discriminant of the given equation is 57.

57 is greater than 0 and square root of 57 will result real number.

So, the correct choice is C: The discriminant is greater than 0, so there are two real roots.
