Answer: x ≈ 18 ft

Step-by-step explanation:

We will use our trig knowledge to solve this.

The man is standing 10 ft away, but we also need to add the 5 ft shadow as well as that is a point on our triangle.

We can set up a simple trig equation of: tan(50) = x/15

x being the height of the lamppost.

Now we solve.

tan(50) = 1.1918

1.1918 *15 = x

x = 17.876

Now round to the nearest foot.

x ≈ 18 ft

Can someone explain and answer please??

Simplify the ration expression
\frac{3x-6}{x-2}

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator

when you do so, the result is
\frac{3 *(x-2)}{x-2}

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

\frac{x-2}{x-2} =1
however, only when x \neq 2
since \frac{0}{0} \neq 1

when you cancel out the x-2, you're left with 3

hence, your answer is C

7n2 + 5 = 453<br> Solve the quadratic function
Reptile [31]

7n^2 + 5 = 453

Subtract 5 from both sides:

7n^2 = 448

Divide both sides by 7:

N^2 = 64

Take the square root of both sides:

N = 8

Step-by-step explanation:

[ Refer to the attachment for steps ]

  • We have to eliminate the highest degree coefficient in each step.

  • And as in division of normal numbers we subtract the things here we do the same ,

but while subtracting we have to take care about the signs !

  • The negative sign changes the negative sign into positive sign and positive sign into negative sign.

  • Whereas , a positive sign don't changes the sign.
