What is the measure of each exterior angle in a regular 10-sided polygon?

Mathematics
1 answer:
Semenov [28]3 years ago
6 0

Answer:

Option D. 36°

Step-by-step explanation:

we know that

The sum of the exterior angles of a polygon must be equal to 360 degrees

In a regular polygon all the exterior angles are congruent

so

To obtain the measure of each exterior angle divide 360 by the number of sides

In this problem the number of sides is 10

360/10=36°

A parallelogram has one angle that measures 55°. What are the measures
nikklg [1K]

Answer:

this is an example:

In a parallelogram, like in any other quadrilateral, the sum of the measures of the interior angles is 360 degrees. Also in a parallelogram, if you have one angle that is 65 degrees, you must also have a second angle that is 65 degrees, so the sum of those two angles is 130 degrees. The sum of the other two angles, which are of identical measure, is then 360 minus 130 equals 230 degrees. Divide 230 by 2 to get the measure of the other two angles.

The height h above the roadway of the main cable of the Golden Gate Bridge can be modeled by the function h(x) =1/9000x2 - 7/15x
julia-pushkina [17]
H(x) = 1/9000x^2 - 7/15x + 500 = 1/9000(x^2 - 4200x + 4500000) = 1/9000(x^2 - 4200x + 4410000 + 90000) = 1/9000(x - 2100)^2 + 1/9000(90000) = 1/9000(x - 2100)^2 + 10

h(x) = 1/9000(x - 2100)^2 + 10

Round these numbers to the nearest tenth.<br> a) 74.3472<br> b) 98.759
Harman [31]

Answer:

a) 74.3

b) 98.8

Step-by-step explanation:

The tenth decimal place is the first place immediately to the right of the decimal point. When rounding, you first need to look at the number to the right of the place you wish to find. If the number in this spot is 5 - 9, round the number in the tenth decimal place up one unit. If the number is 0 - 4, keep the number in the tenth decimal place the same. Finally, remove all of the numbers to the right of the tenth decimal place.

a) 74.3472

        ^ tenth

The next number to the right (4) is not big enough to round up

a) 74.3

b) 98.759

         ^ tenth

The next number to the right (5) is big enough to round up

b) 98.8
