Hello There! So your question says you first have to find the the angles of all the triangles , then find there sum ( add them) then do the same for the quadrilaterals, then the hexagons, pentagons and octagons, they are asking if all of them have the same answer or not! Now you need to construct a shape using that sum. And you have to write down the function machine, the number of sides you calculated and number of angles! And then explain that do you think that it is correct!

Answer:
The number is 60
Step-by-step explanation:
65% out of what number is 39
.65 * n = 39
Divide by .65 on each side
.65*n/.65 = 39/.65
n = 60
Answer:
see explanation
Step-by-step explanation:
(5)
Since ∠EBA = 90° then ∠ABD = 90° ( straight angle ) and
∠ABC + ∠CBD = ∠ABD, that is
2x + 3x - 10 = 90, simplifying
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20, thus
∠ABC = 2x = 2 × 20 = 40°
∠CBD = 3x - 10 = (3 × 20) - 10 = 60 - 10 = 50°
(6)
4x - 18 = 3x + 7 ( vertical angles are congruent )
Subtract 3x from both sides
x - 18 = 7 ( add 18 to both sides )
x = 25
7y = 5y + 28 ( vertical angles are congruent )
Subtract 5y from both sides
2y = 28 ( divide both sides by 2 )
y = 14
440 repeat 11 more times.
400+(400*.1)=440 repeat 11 more times. Remember to use a new value each time.
Vacations can get expensive fast. The average cost per person for a week-long vacation is about $1,200 annually. So, if you've got a family of five, you'll need to sock away at least $6,000 for transportation, hotels, meals, and amusement parks.
Financial experts suggest that the average family vacation costs between 5-10% of your total income. If your family makes $40,000 per year then experts say your yearly family vacation budget should average between $2,000-$4000.
