<u>Answer:</u>

The correct answer option is a. 20.5 feet.

<u>Step-by-step explanation:</u>

We are given that the angle of elevation of the ladder is 70° and the height of the ladder is 25 feet from the ground.

We are to find the distance of the building from the base of the ladder.

For this, we will use tan:

tan 70 = \frac { 2 5 } { x }

x = \frac { 2 5 } { tan 7 0 }

x = 20.5 feet

Answer:

a. 20.5

Step-by-step explanation:

because this will form a right triangle we can use tan (opposite over adjacent) so an equation we could set up would be tan(70)=25/x

therefore we can just solve the equation which would give us 20.45. so if we round it the answer would be a

The top row contains the product of x^{2} with each term of the expressions x^{6}+ x^{4}+ x^{2} and bottom row contains the product of -1 with each term of expression x^{6}+ x^{4}+ x^{2} .

The final result will be the sum of terms of both rows as shown below:

( x^{6}+ x^{4} + x^{2} )( x^{2} -1) \\  \\ &#10;= x^{2} ( x^{6}+ x^{4} + x^{2} )-1( x^{6}+ x^{4} + x^{2} ) \\  \\ &#10;= x^{8}+ x^{6}+ x^{4}- x^{6}- x^{4}- x^{2}  \\  \\ &#10;= x^{8}- x^{2}

So the correct answer is option D
