Answer:

(A) 2 meter

Step-by-step explanation:

It is given that the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high.

Let the measure of bottom of the ladder from the wall be x, then using the trigonometry, we have

$\frac{CB}{AB}=tan72^{\circ}$

$\frac{6}{x}=tan72^{\circ}$

$\frac{6}{x}=3.077$

$x=\frac{6}{3.077}$

$x=1.94$

$x$ ≈ $2m$

Thus, option A is correct.

Tell whether the given value is a solution of the inequality. a/6 > -4; a = -18

balandron [24]

First we simplify the inequality

1. multiply 6 by the other side of the inequality (-4)

Now we have ...

a > -24

Anything that can be a solution to the inequality must be greater than -24

-18 is greater than -24

This means that, YES! a = -18 IS a solution to the inequality
