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

Using the data: 2, 2, 3, 3, 3, 4, 5, 6, 6, 19<br><br> What is Q1 and Q3

Anettt [7]

Answer:

$Q_1=2$

$Q_3=6$

Step-by-step explanation:

Notice that we already have the data sorted from least to greatest.

Now to find Q1 and Q3 we can use the following formulas

For a set of data ordered from least to greatest of the form $X_1, X_2, ..., X_n$

Where n is the total number of data

$Q_1=X_{\frac{1}{4}(n+1)}$

In this case $n=10$

So:

$Q_1=X_{\frac{1}{4}(10+1)}$

$Q_1=X_{2.75}$

Round the nearest whole and get:

$Q_1=X_{3}$

$Q_1=3$

For Q3 we have:

$Q_3=X_{\frac{3}{4}(n+1)}$

$Q_3=X_{\frac{3}{4}(10+1)}$

$Q_3=X_{8.25}$

Round the nearest whole and get:

$Q_3=X_{8}$

$Q_3=6$
