Answer:
Angle 9: 60°
Angle 10: 30°
Side = radius = 40sqrt(x/3)
Area = [800sqrt(3)]x
Step-by-step explanation:
Total angle in a hexagon:
(6 - 2) × 180
720
Each interior angle:
720/6 = 120
angle 9 = 120/2 = 60
Angle 10 = 60/2 = 30
sin(60) = 20sqrt(x)/r
r = 20sqrt(x) ÷ sqrt(3)/2
r = 40sqrt(x/3)
Side:
sin(30) = ½s/(40sqrt(x/3))
½s = 20sqrt(x/3)
s = 40sqrt(x/3)
Area = (3sqrt(3))/2 × s²
Area = 3sqrt(3)/2 × 1600x/3
Area = [800sqrt(3)]x
Where is the questoin pls tell me
Answer:
2.3
Step-by-step explanation:
Time taken by Ella is 0.6 hour
<u>Solution:</u>
Lily finished a task in 
hour
Ella finished it in 
of time Lily took
<em><u>To find: time taken by Ella to finish the task</u></em>
Let "L" be the time taken by Lily
Time taken by Lily = L = 
From given statement,
Time taken by Ella to finish the task is of time Lily took
Therefore,
Time taken by Ella = of time taken by Lily
Thus time taken by Ella is 0.6 hour
