Answer:
Common ratio = 3/4
Step-by-step explanation:
The nth term of a geometric progression is given by
an = a1 . rn - 1
Where;
an = the nth term
a1 = the first term
r = common ratio
n = the number of terms in the series
Common ratio, r = the ratio of the second term to the first term
= a2 : a1
Given from the series,
a2 = 48
a1 = 64
Common ratio, r = 48 : 64
= 48/64 = 3/4

Answer:
Vertical angles
x=25
Step-by-step explanation:
Adjacent angles are angles that are next to each other. Vertical angles are angles that are opposite each other.
In this problem, the angles are opposite each other. Therefore, they are <u>vertical</u> <u>angles.</u>
Since they are vertical angles, they are congruent, or equal. So, we can set them equal to each other and solve for x.
75=4x-25
To solve for x, we have to isolate x. First, move all the constants to the same side, by adding 25 to both sides.
75+25=4x-25+25
75+25=4x
100=4x
Now, 4 and x are being multiplied. To undo this, divide both sides by 4.
100/4=4x/4
100/4=x
25=x
The angles are vertical and x=25
