1.

, which implies that the sides could be

and

. (There are theoretically an infinite number of side-lengths, though--in general, for any polynomial or reciprocal of a polynomial

,

and

is valid. However, the set provided makes the most sense.)
2. Profit is the difference between cost and revenue. For revenue,

, so revenue equals

, so profit equals
1. The formula is 180(n-2)/n, where n=sides. so hexagon has 6 sides, so it would be 180(6-2)/6=180(4)/6=720°/6=60° per side.
2. The sum of measures of ANY polygon is ALWAYS 360°
3. Notice that there are 6 sides. This means the total interior angles are 720°. x=127°
4. now, it's talking about a SINGLE exterior angle. So the interior angle is always 360/n, where n=5 here, so 360=5=72°
120 hours
because 24x5=
120
I would need more information since you must use trig to find the value
I would need to know where they are located in order to find cos of H correctly
a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81
b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1
