Step by step explanation:

$\text{Given that,}\\\\\text{5th term} = ar^{5-1} = ar^4 = 48~~~~~~~~...(i)\\ \\\text{8th term} = ar^{8-1} = ar^7 = 384~~~~~~~...(ii)\\\\\text{1st term,}~ a = ?\\\\\text{Common ratio,}~ r = ?\\\\(ii) \div (i):\\\\~~~~~~\dfrac{ar^7}{ar^4}=\dfrac{384}{48}\\\\\implies r^{7-4} = 8\\\\\implies r^3 = 8\\\\\implies r^3 = 2^3\\\\\implies r =2\\\\\text{Substitute r = 2 in eq (i):}\\\\~~~~~~a\cdot 2^4 = 48\\\\\implies 16a =48\\\\\implies a = \dfrac{48}{16}\\\\\implies a = 3\\$

Find the value of x. A.20 B.25 C.18.75 D.22.5

miss Akunina [59]

The two equations are vertical angle, which would be equal to each other.

Set the equations to equal and solve for x:

5x -10 = 3x +40

Subtract 3x from both sides:

2x -10 = 40

Add 10 to both sides:

2x = 50

Divide both sides by 2:

x = 50 / 2

x = 25

The answer is B. 25
