Answer:
12°
Step-by-step explanation:
So, for your 30-gon, the interior angles total up to (30-2) * 180 = 5040. Each interior angle is that total divided by the number of interior angles, or 5040/30 = 168º:
<u>The measure of each exterior angle is the total divided by the number of angles, or 360/30 = 12º.</u>
Well you have runner 1 in lane 1. runner 1 in lane 2 and so on. so it becomes 1,1 1,2 1,3 1,4 1,5 1,6 and then 2,1 2,2 2,3 2,4 2,5 2,6 then 3, and so on
Answer:
Maximum volume error = ±540 cm³
Relative error = 0.02
Percentage error = 2%
Step-by-step explanation:
Relative error : The ratio of volume error to the total volume.
Percentage error: The product of relative error and 100.
The volume of a cube is = 
v =x³
Differentiate with respect to x


Here are x = 30 cm and dx= ±0.2 cm
∴ dv = 3×(30 cm)² (±0.2 cm)
=±540 cm³
The volume of the cube = 30³ cm ³ = 27,000 cm³
Then the relative error


= 0.02.
The percentage error
= (0.02×100)
=2%
Answer:
39cm
Step-by-step explanation: 19cm+15cm+5cm=39
