Answer:

6 m

Step-by-step explanation:

The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse.

Hence, sin 30° = \frac{a}{c}

                         = \frac{a}{12}

                      a = 12sin30°

                      a = <u>6m</u>

Find a linear inequality with the following solution set. Each grid line represents one unit.
ikadub [295]

The linear inequality in standard form is: x + y < -2 or x + y + 2 < 0

<h3>How to Write a Linear Inequality?</h3>

To determine what sign to use, follow these rules:

  • Use "<" or ">" when the boundary line is dotted or dashed.
  • Use "<" or "≤" when the shaded area is under the boundary line (dotted or dashed).
  • Use "≤" or "≥" when the boundary line is not  dotted or dashed.
  • Use ">" or "≥" when the shaded area is above the boundary line (dotted or dashed).

The graph given has the following features:

  • It has a boundary line that is dotted/dashed.
  • It has a shaded area that is under the boundary line.
  • Thus, the inequality sign we would use is, "<".

Find the slope:

Slope (m)= rise/run = -(2 units) / (2 units).

Slope (m) = -1.

The y-intercept (b) = -2.

Substitute m = -1 and b = -2 into y < mx + b:

y < (-1)x + (-2)

y < -x - 2

Rewrite

x + y < -2

x + y + 2 < 0
