Answer:

Step-by-step explanation:
Given
The attached triangle
Required
Find x
Considering angle 30 degrees,


Using the tangent formula:

Make x the subject




As shown in the figures given :
For Figure 1 : perimeter = 8 units [As can be seen in the figure]
For figure 2(with 2 octagons) : perimeter = 8 × 2 - 1 = 15 units [since 1 side is common ]
For figure 2(with 3 octagons) : perimeter = 8 × 3 - 2 = 22 units [since 2 sides is common ]
If one more octagon is added
then perimeter = 8 × 4 - 3 = 29 units [since 3 sides will be common ]
Answer:

And if we want to find

Answer:
1 1/2
Step-by-step explanation:
divide 9 by 6 (because its 6 miles per hour) you get 1 1/2. so it would be 1 1/2 hours or 1/5 hours
I would say Ben because the chance of the numbers being 1,2,3,4,5, 6 would be extremely low
