 If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360°

Answer:

360 degrees is  sum of the measures of the exterior angles of any convex polygon.

Step-by-step explanation:

Convex Polygon:

  • A convex polygon is a polygon with all its interior angle less than 180 degrees.
  • Thus, all the vertices of the polygon will be away from the interior of the polygon.
  • If all the angles are not less than 180 degrees then it becomes concave polygon.
  • Example: Triangle is a convex polygon with three sides.

Exterior angle sum Property:

  • If we extend the side of the polygon, then the angle formed by the extended side and polygon side is an exterior angle.
  • The sum of all the exterior angles if a convex polygon is 360 degrees.
  • If this convex polygon is a regular polygon, then the sum is 360 degrees and each exterior angle is equal to \frac{360}{n}, where n is the number of sides in regular polygon.

I’m trying to find the answer for these 2 questions. Please!
Elanso [62]

1) For the second semester, we recognize that the number of actual students (75) is 15 times the ratio number (5) used to represent it. We also recognize that the total number of ratio units (5+4) for the second semester is the same as the total number (2+7) for the first semester.

If each ratio unit reprsents 15 students, in the first semester there were

... 2×15 = 30 students in art

... 7×15 = 105 students in gym

2) We can use the same sort of logic for the second problem as for the first. 6 ratio units represents $936 before money is moved, so each represents $156.

After the move, the account balances are

... savings: 4×$156 = $624

... checking: 3×$156 = $468

_____

Since the numbers of "ratio units" add to the same value in each case for both problems, we can solve this the way we have done—by determining the value a "ratio unit" stands for. If the problem had been posed differently, we might have been required to find the total number of students (dollars), then reapportion them according to the new ratios.

Essentially, when you have

... part1 : part2

you can find the total from

... part1 : total = part1 : (part1 + part2)

or

... (part1 + part2)/(part 1) × (actual value of part 1) = (actual value of total)

State the domain and range for the function f(x) = 2x2 – 7. Show all steps, please.
polet [3.4K]
2x^2 - 7 

we can plug any values of x into this The domain is All Real x.

The graph will be a parabola opening upwards with a minimum value  when x = 0  and  f(x) will be = -7

so the range is  f(x) <= -7    or  (-∞, -7]
