Answer:
The formula is:
Step-by-step explanation:
The geometric sequences are those in which the division between the terms 
and 
of the sequence are equal to a constant common reason called "r"
The geometrics secencias have the following form:
Where 
is the first term of the sequence
In this sequence we have the following terms
1.2, 3, 7.5, 18.75
Then notice that:
Then:
and 
Finally the formula is:
Once you get to "5" you start rounding up, so the least would be 250.
Answer:
Angle f= 66
DE=10
Step-by-step explanation:
So first I think it's an isosceles triangle to 2 sides will have the same length.
For the angle I added 90 and 24 and subtracted them from 180.
Well to simplify it we combine the x's: 4x+11, then to solve for x:
4x= -11
x= -11/4
