The exterior angles of a regular pentagon has a measure of 360-108= 252 degrees
the sum of these exterior angles will be 5*252=1260 degrees
a regular nonagon (9-gon) has the exterior angles measure of 360 -140 = 220 degrees
the sum of these exterior angles of a nonagon will be equal 9*220=1980 degrees
so from these result that
the sum of the measures of the exterior angles of a regular 5-gon is less than the sum of the measures of the exterior angles of a 9-on
hope this will help you
To find the average, add them all up. 13 + 7 + 12 + 9 + 8 + 8 + 16 = 73
Then divide by how many numbers there are, 73 divided by 7 = 10.4285714286
10.4285714286 rounded to the nearest tenth = 10.4
Hope this helps :D
Answer:
=13x-5
Step-by-step explanation:
Answer:
y= -3x-20
Step-by-step explanation:
°First find the gradient between the two points
Gradient= - 3
°Using the formula y= mx+c substitute the gradient into the equation. You'll get something like this: y=-3x+c
°Substitute the point (-8;4) in the above equation. You'll get something like this : 4=-3(-8) +c
°Calculate the value of c. It'll give you c=-20
°Substitute c=-20 in the equation
Final answer is y= - 3x-20
Surface area of a sphere = 4πr² = 4π(15)² = 900π m²
Surface area of a sphere = 4πr² = 4π(10)² = 400π m²
