Answer:
8
Step-by-step explanation:
Measure of one interior angle of a regular polygon of n sides:
(n - 2)180/n
Measure of one exterior angle of a regular polygon if n sides:
360/n
"the interior angle is thrice the exterior angle"
(n - 2)180/n = 3 * 360/n
(n - 2)180 = 3 * 360
n - 2 = 3 * 2
n = 8
The number of sides is 8.
Answer:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.
Step-by-step explanation:
We have the equation:
so:
and:
This equation has one solution.
Answer:
25 km
Step-by-step explanation:
Distance covered in 20 min = 5 km
Distance covered in 1 min = 5/20 km or 1/4 km.
Distance covered in 100 min =
1/4 km x 100 = 25 km
So percent means parts out of 100
x%=x/100
so we jsut have to find
(red)/(total)
add 23+52+34+61+30=200
red=52
52/200
make bottom number 100
26/100=26%
answer is 26%
