Answer: The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.
Step-by-step explanation: Hopefully this helps!
52 ×.65= X
The answer would be $80. Hope i could be helpful :)
Answer: 43
Explanation: All triangles add up to 180. We can subtract angle Z to get 86. Since X and Y are equal, we can divide 86 by 2.
To find the cost of each item, you will create an equation in terms of the t-shirt.
Each item is related to the price of the t-shirt.
SWEATPANTS + SWEATSHIRT + TEE SHIRT = TOTAL COST
(2t - 5.50) + (t + 8) + t = $76.50
4t + 2.50 = 76.50
- 2.50 -2.50
<u>4t</u> = <u>74</u>
4 4
t = $18.50
The tee shirt is $18.50.
The sweatpants are 2 x $18.50 - 5.5 = $31.50
The sweatshirt is $18.50 + 8 = $26.50
