Answer: x = 5/3 OR x = -1

Step-by-step explanation: to solve this, we can rewrite the absolute value as two inequalities (one equal to the positive value, one equal to l the negative value) and solve each:

| 9x - 3 | = 12 becomes:

9x - 3 = 12

9x = 12 + 3

9x = 15

x = 15/9

x = 5/3 OR 1.66 as decimal

and now the other:

9x - 3 = - 12

9x = -12 + 3

9x = - 9

x = -9/9

x = -1

Because an equality is given, when we solve for x, there are technically just two possible values that would meet the conditions. Either 5/3 or - 1

Answer: 114.37 ft

Step-by-step explanation:

If we model this situation as a right triangle, where the hypotenuse is the length of the ladder ( $110 ft$ ), the opposite leg is the height the ladder will reach $h$ , and the adjacent leg is the distance between the base of the ladder and the building ( $28 ft$ ); we have two options:

1) Using trigonometric functions, since we are given the angle $\theta=75\°$

2) Using the Pithagorean Theorem

Any of the options will give a similiar result. So, let's choose the Pithagorean Theorem:

$(hypotenuse)^{2}=(opposite-leg)^{2}+(adjacent-leg)^{2}$

$(110 ft)^{2}=(h)^{2}+(28 ft)^{2}$

Isolating $h$ :

$h=\sqrt{(110 ft)^{2}-(28 ft)^{2}}$

$h=106.37 ft$

Adding to this height the extra height of $8 ft$ (since the base of the ladder is at this distance above the ground, perhaps held by a firefighter truck):

$h=106.37 ft+8 ft=114.37 ft$ This is the height the ladder will reach
