Speed of boat 



Answer:
3/5
Step-by-step explanation:
absolute value is always positive
Answer: There are 10 sides
---------------------------------------------
x = measure of each interior angle
y = measure of each exterior angle
We know that x = 4y as "each interior angle is four times the measure of each exterior angle"
The interior and exterior adjacent angles are supplementary
x+y = 180
4y+y = 180
5y = 180
5y/5 = 180/5
y = 36
If y = 36, then
n = 360/y
n = 360/36
n = 10
Let x be the current price of the product
1.15 * x = $2..88
So when rearranging the equation, you get:
x = 2.88/1.15 = $2.50 (to the nearest cent)
The sum of interior of all angles in a triangle = 180
Given 3 angles = <span>80°, 2x + 2°, and 5x°
To find x:
</span><span>80°+ 2x + 2 + 5x = 180
7x + 82 = 180
7x = 98
x = 14
answer
x = 14 </span>
