Answer:
a₁ = 1
r = 3
Step-by-step explanation:
Since it’s a geometric series then
a₁ = 1 ( because 1 is the first term of the series)
3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.

Answer:
The measure of the angles in degree is 57.5 degrees
Step-by-step explanation:
If two angles are congruent, they are equal in value
Let the number be x
2x + 3 = 3x-54.5
Thus;
3x-2x = 54.5 + 3
x = 57.5

Answer:
A. 1
Step-by-step explanation:
3(x+1)=-2(x-1)+6
3x+3=2x-2+6
x+3=4
x=1
