Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric progression is
•  = a₁
 = a₁ 
where a₁ is the first term and r the common ratio
given a₄ = 24, then
a₁ = 24 → (1)
 = 24 → (1)
Given a₈ =  , then
, then
a₁ =
 =  → (2)
 → (2)
Divide (2) by (1)
 =
 =  =
 = 
Hence r = ![\sqrt[4]{\frac{1}{81} }](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%5Cfrac%7B1%7D%7B81%7D%20%7D) =
 = 
Substitute this value into (1)
a₁ × ( )³ = 24
 )³ = 24
a₁ ×  = 24, hence
 = 24, hence
a₁ = 24 × 27 = 648
 
        
             
        
        
        
Angles TRS and VRW are vertical angles, so we can set them equal to each other to get x:
x+40=3x
40=2x
20=x
So the value of x is 20
