Answer:

$x = - 6$

$x = 12$

$x = 8$

$x = - 21$

$x = 18$

$x = - 2$

$x = 40$

$x = - 3$

$x = -21$

$x = 2$

$x = - 18$

$x = - 7$

$x = 6$

$x = 10$

$x = 3$

Step-by-step explanation:

$1.$

$- 7x + 16 = 58$

$- 7x = 58 - 16$

$- 7x = 42$

$\frac{ - 7x}{ - 7} = \frac{42}{ - 7}$

$x = \frac{ 42}{ - 7}$

$x = - 6$

$2.$

$- 2x + 15 = - 9$

$- 2x = - 9 - 15$

$- 2x = - 24$

$\frac{ - 2x}{ - 2} = \frac{ - 24}{ - 2}$

$x = \frac{ - 24}{ - 2}$

$x = 12$

$3.$

$5x - 4 = 36$

$5x = 36 + 4$

$5x = 40$

$\frac{5x}{5} = \frac{40}{5}$

$x = \frac{40}{5}$

$x = 8$

$4.$

$25 - 3x = 88$

$- 3x = 88 - 25$

$- 3x = 63$

$\frac{ - 3x}{ - 3} = \frac{63}{ - 3}$

$x = \frac{63}{ - 3}$

$x = - 21$

$5.$

$- 11 = 7 - x$

$7 - x = - 11$

$- x = - 11 - 7$

$- x = - 18$

$\frac{ - x}{ - 1} = \frac{ - 18}{ - 1}$

$x = \frac{ - 18}{ - 1}$

$x = 18$

$6.$

$65 + 15x = 35$

$15x = 35 - 65$

$15x = - 30$

$\frac{15x}{15} = \frac{ - 30}{15}$

$x = \frac{ - 30}{15}$

$x = - 2$

$7.$

$\frac{1}{2} x - 18 = 2$

$\frac{1}{2} x = 2 + 18$

$\frac{1}{2} x = 20$

$\frac{1}{2} \times 2x = 20 \times 2$

$x = 40$

$8.$

$\frac{2}{3} x - 10 = - 12$

$\frac{2}{3} x = - 12 + 10$

$\frac{2}{3} x = - 2$

$x = - 2( \frac{3}{2} )$

$x = - 3$

$9.$

$6 - \frac{1}{3} x = - 1$

$- \frac{ 1}{3} x = - 1 - 6$

$- \frac{1}{3} x = - 7$

$x = - 7( - \frac{3}{1} x)$

$x = 21$

$10.$

$4 - 9 x= - 14$

$-9x = - 14 - 4$

$-9x = - 18$

$\frac{-9x}{-9} = \frac{ - 18}{-9}$

$x = \frac{ - 18}{-9}$

$x = 2$

$11.$

$11 - x = 29$

$- x = 29 - 11$

$- x = 18$

$\frac{ - x}{ - 1} = \frac{18}{ - 1}$

$x = \frac{ 18}{ - 1}$

$x = - 18$

$12.$

$- 9- 11 x= 68$

$- 11x = 68 + 9$

$- 11x = 77$

$\frac{ - 11x}{ - 11} = \frac{77}{ - 11}$

$x = \frac{77}{ - 11}$

$x = - 7$

$13.$

$45 + \frac{5}{6} x = 50$

$\frac{5}{6} x = 50 - 45$

$\frac{5}{6} x = 5$

$x = 5( \frac{6}{5} )$

$x = 6$

$14.$

$- 5x + 17 = - 33$

$- 5x = - 33 - 17$

$- 5x = - 50$

$\frac{ - 5x}{ - 5} = \frac{ - 50}{ - 5}$

$x = \frac{ - 50}{ - 5}$

$x = 10$

$15.$

$95 = - 4 + 33x$

$- 4 + 33x = 95$

$33x = 95 + 4$

$33x = 99$

$\frac{33x}{33} = \frac{99}{33}$

$x = \frac{99}{33}$

$x = 3$

What is measure of side A?

Ira Lisetskai [31]

<u>Answer:</u>

The correct answer option is c. a = 11.94.

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

We are given a right angles triangle with an angle ABC equal to 58 degrees and side length AC known to be equal to 19.1.

We are supposed to find the length of side a.

Side AC, opposite to angle ABC, will be the perpendicular and BC will be the base so we will use the formula of tan to find b.

$tan 58 = \frac{19.1}{a}$

$a = \frac{19.1}{tan 58}$

$a=11.94$

HELP !!! | 20 Points.

RUDIKE [14]

Answer:

No. The ladder is too steep.

Step-by-step explanation:

Length of ladder = 17 feet. This is the hypotenuse.

Side a of a right triangle = 16.6

To answer this, you need one of the trigonometric functions.

Opposite = 16.5

hypotenuse = 17

The function you need is the sine function.

Sin(theta) = opposite / hypotenuse

sin(theta) = 16.5 / 17

Sin(theta) = 0.97059

theta = sin-1(0.07059)

theta = 76.07

No the ladder is too steep.
