The sum of all interior angles is (n-2)x180 while n=number of sides. So (6-2)x180=720. The angles you have add up to 588. All you need to do now is 720-588. x=132

we know that

The sum of all interior angles in the polygon is equal to the formula

$(n-2)*180\°$

where

n is the number of sides of the polygon

In this problem we have

$n=6$

substitute the value in the formula

$(6-2)*180\°=720\°$

Find the value of x

$720\°=x\°+108\°+113\°+132\°+75\°+160\°\\720\°=x\°+588\°\\x\°=720\°-588\°\\x=132\°$

therefore

the answer is

the measure of x is $132\°$

Factor to solve: x² + 18x +27 = 8x +3

patriot [66]

Answer: $x=-4$ $or$ $x=-6$

Subtract 8x+3 from both sides

$x^2+18x+27-(8x+3)=8x+3-(8x+3)$

$x2+10x+24=0$

Factor left side of equation

$(x+4)(x+6)=0$

Set factors equal to 0

$x+4=0$ $or$ $x+6=0$

Final Answer: $x=-4$ $or$ $x=-6$

Round the fraction 7 4/5 to the nearest whole number

Over [174]

Im not sure if you are saying 74/5 or 7 and 4 fifths but in the case you'r saying 74/5 you would first round to see the highest number that 5 can go to without being a decimal. Which would be 70 so you would count how many times 5 can go into 70, which would be 14, so the left over is 4/5 so you would check to see if it can be simplified which it can't so the final answer is 14 and 4/5

the cost to rent a hall for school functions is 60$ per hour. write an expression for the cost of renting the hall for h hours.

Firlakuza [10]

The expression for the amount of time rented would be:
C=60(h), I choose this expression because C would stand for cost, 60 for the amount per hour, and h for the piece of expression being given. Now when you need to find the amount per hour, the brackets means to times; so you'd plug in the hour needed to be found in h, and times 60 by the hour.

Your table should look like this :
COST PER HOUR | HOURS | COST
$60    | 2    | $60 x 2 = $120
$60     |    6 |    $60 x 6 = $360
$60    | 8    | $60 x 8 = $480
$60    |    10 | $60 x 10 = $600

Iteru [2.4K]

Answer:

The answer is 65.75

Step-by-step explanation:

Since tq is perpendicular to PR then qtsr becomes square

Then

$qr = 30 \: \: \: \: \: and \: qt = 30 \\$
