An architect plans to make a drawing of the room of a house. The segment LM represents the ceiling of the room. He wants to cons

aev [14]

Here are the steps

1: Put the compass on Q and make the width equal to the distance from Q to L. Extend line LM towards the left side of L and draw an arc hitting the line segment on the left side of L

2. <span> Without changing the width and position of the compass, draw an arc between L and M.

3. Without changing the width of the compass, put the compass on the point of intersection of the arc and line LM (left side of L). Draw an arc above line LM.

4. Without changing the width of the compass, put the compass on the point of intersection of the arc and line LM (right side of L). Draw an arc above line LM.

5. Use a straight edge to make a line from the intersection of the two arcs above line LM to Q intersecting through L along the way. </span>

Please help me with problem 1 of Systems of Linear Inequalities

matrenka [14]

To solve correctly, graph both inequalities. The solution is where they overlap. <em>See attachment for graph. </em>Which coordinate is plotted in the overlapping section?

If you don't have the tools to graph them, then plug each coordinate into both inequalities. The coordinate that makes a true statement for BOTH inequalities, is the answer.

(0, 4): 4 > -2 TRUE 0 + 4 < 4 FALSE

(-3, 5): 5 > -2 TRUE -3 + 5 < 4 TRUE THIS IS THE ANSWER!

(1, 4): 4 > -2 TRUE 1 + 4 < 4 FALSE

(-2, -3): -3 > -2 FALSE

A triangular plot of land has one side along a straight road measuring 147147 feet. A second side makes a 2323degrees° angle wit

ch4aika [34]

Answer:

81.23 ft and 77.88 ft long

Step-by-step explanation:

The sum of the internal angles of a triangle is 180 degrees, the missing angle is:

$a+b+c=180\\a+23+22=180\\a=135^o$

According to the Law of Sines:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}= \frac{C}{sin(c)}$

Let A be the side that is 147 feet long, the length of the other two sides are:

$\frac{A}{sin(a)}= \frac{B}{sin(b)}\\B=\frac{sin(23)*147}{sin(135)}\\B=81.23\ ft\\\\\frac{A}{sin(a)}= \frac{C}{sin(c)}\\C=\frac{sin(22)*147}{sin(135)}\\C=77.88\ ft$

The other two sides are 81.23 ft and 77.88 ft long
