Find the number of sides for a regular polygon whose interior angles each measure 10 times each exterior angle

gavmur [86]

Answer:

22 sides

Step-by-step explanation:

The expression to find an interior angle of a polygon is:

$\frac{(n-2)*180}{n}$

The expression to find an exterior angle of a polygon is:

$\frac{360}{n}$

Please note that "n" represents the number of sides the polygon has.

We can use these two expressions to set up an equation.

$\frac{(n-2)*180}{n}=10(\frac{360}{n})$

Multiply both sides by "n":

$(n-2)*180=10n(\frac{360}{n})$

Now, distribute:

$180(n)-180(2)=\frac{3600n}{n}\\180n-360=3600$

Divide both sides by 10:

$\frac{180n}{10}-\frac{360}{10}=\frac{3600}{10}\\$

$18n-36=360$

Add 36 to both sides:

$18n=360+36\\18n=396$

Divide both sides by 18:

$n=22$

The polygon has 22 sides

Brandy set her watch 4 seconds behind and it falls behind another 1 second every day. How many days had it been since brandy las

kari74 [83]

Answer:

18 days

Step-by-step explanation:

Let x represent number of days.

We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall $1x$ seconds behind in x days.

We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total $x+4$ seconds in x days.

Since Brady's watch is 22 seconds behind, so we will equate $x+4$ by 22 to solve for x as:

$x+4=22$

$x+4-4=22-4$

$x=18$

Therefore, Brandy set her watch 18 days ago.

In a 45-45-90 triangle, what is the length of the hypotenuse if the length of one of the legs is 5 in.?

IgorC [24]

You could use the Pythagorean Theorem to find this. Since the two legs will be the same length:
5² + 5² = c²
25 + 25 = c²
50 = c²
√50 = √c²
5√2 = c
so the hypotenuse length is 5√2
