Answer:
Missing number ⇒ 27
Step-by-step explanation:
Given sequence is:
1, 1, 4, 8, 9 , ?, 16, 64
We need to find the missing number of the sequence.
Solution:
We can see the series consist numbers 1, 2, 3, 4, 5.. of power 2 and 3 each respectively. So, the series is
such that

Therefore, missing number is 
Answer:
x = 8.7
Step-by-step explanation:
Reference angle = 30°
Opposite side length = x
Adjacent side length = 15
Apply trigonometric function, TOA:
Tan 30° = Opp/Adj
Plug in the values
Tan 30° = x/15
Multiply both sides by 15
15*Tan 30° = x
8.66025404 = x
x = 8.7 (nearest tenth)
