The sum of the interior angles of a hexagon is 720 degrees. If 3 angles are congruent, each with measure x degrees, and the other 3 angles are also congruent to each other, each with measure 2x degrees, then the total sum of all 6 angles would be 3x + 3(2x) = 9x. If this is equal to 720, then x = 80 degrees, while 2x = 160 degrees.
Therefore, there are 3 80-degree angles and 3 160-degree angles.

Each leg of a 45°-45°-90° triangle measures 14 cm. What is the length of the hypotenuse?

4vir4ik [10]

For a 45-45-90 angle the hypotenuse is s * square root of 2

so the hypotenuse is 14 * square root of 2 or 19.8

Charlotte purchased a pool for $7680 using a six-month deferred payment plan with an interest rate of 20.45%. She did not make a

Georgia [21]

$7680:100%=$x:120.45%, 100x=7680*120.45, x=(7680*120.45)/100, x=$9250.56
Cost of the pool with interest rate is $9250.56.
3yr*12mo=36mo
$9250.56/36mo=256.96$/mo

 Charlotte's monthly payment will be $256.96.

Solve for y: 8 = x-y

AnnyKZ [126]

Answer:

The correct answer is:

y= x-8

Step-by-step explanation:

We have the equation: 8 = x-y

By clearing the equation for y (subtracting x both sides of equation) we have:

8 - x = -y (1)

Multiplying (1) by -1

-8+x = y (2)

Re-arranging (2), finally we have:

y= x-8
