Hi there!
As I saw in some other questions, I assumed this question is about unit rates..
So, the answer to this is 750 kb/m
Hope this helps!
Answer:
The angle F = 47.25°
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that f =42inches and e = 39 inches
Given that ∠E = 43°
By using sine rule


⇒
Cross multiplication , we get
⇒ 39 sin F = 42 × sin 43°

⇒ sin F = 0.734459
<u><em>Step(ii):-</em></u>
⇒ sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)
⇒ F = 47.25
The angle F = 47.25°

Step-by-step explanation:
Answer: Each time the pentagon is rotated , it maps back onto itself. There are five values of for which the pentagon maps back onto itself. This is the same as the number of sides of the pentagon.
