One exterior angle of a regular pentagon has a measure of (2x). What is the value of x?

777dan777 [17]

x = 36

pentagon has 5 sides . The formula n/360 gives you the measure of each angle in a regular polygon. So in this case n ( stands for number of sides) is 5. Sum of exterior angle of a any polygon is 360. The measure of 1 exterior angle is given. It is 2x.

Now using ALGEBRAIC EXPRESSIONS we can write it as 5/360 = 2x

which is 72=2x

which is 72/2 = x

which is 36 = x

so x = 36.

Answer:

$\displaystyle y=-\frac{1}{2}x+\frac{11}{2}$

Step-by-step explanation:

<u>Equation of the Line</u>

A line of slope m and y-intercept b can be expressed by the equation:

$y=mx+b$

The given line has the equation:

$8x-4y=-24$

Let's express it in the correct form:

$-4y=-24-8x$

Dividing by -4

$y=2x+6$

The slope of this line is m1=2. To find the slope m2 of a line perpendicular to this one, we use the following equation:

$m_1.m_2=-1$

Solving for m2:

$\displaystyle m_2=-\frac{1}{m_1}$

$\displaystyle m_2=-\frac{1}{2}$

The required equation has the form:

$\displaystyle y=-\frac{1}{2}x+b$

To find b, we use the point (3,4) through which the line passes:

$\displaystyle 4=-\frac{1}{2}(3)+b$

$\displaystyle b=4+\frac{3}{2}=\frac{11}{2}$

Thus the equation of the line is:

$\boxed{\displaystyle y=-\frac{1}{2}x+\frac{11}{2}}$
