Let the interior angle be x. x/(180-x) = 13/2 2x= 2340-13x 15x=2340 x=156 exterior angle= 180-156=24 Number of sides=360/24=15 15-sided polygon

Answer: 6.25 or 6 $\frac{1}{4}$

Step-by-step explanation:

Lets do a pro gamer move and convert all fractions to decimals.

We now have 1+1+1.25+1.5+1.5.

From there on we simply do addition.

1+1+1.25+1.5+1.5=6.25

We get 6.25 or 6 $\frac{1}{4}$

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (18, 0)

Point (10, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-5-0}{10-18}$
Subtract: $m=\frac{-5}{-8}$
Simplify: $m=\frac{5}{8}$

5+3=4d please help me

ad-work [718]

So the object of this problem is to find out the value of d.

To do this, first think about 5 + 3. This equals 8, right? So the value of d times 4 has to equal 8.

No other number besides 2 would make sense. 2 would equal d because 4 x 2 is 8, and 5 + 3 is 8.

So you would write the answer as:

5+3=4(2)
