Answer:
Step-by-step explanation:
To find the nth term of a geometric sequence, you have the general formula:
where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):
135 = 
135 = 
135 = 
Now, we can substitute the first term back in:
Step-by-step explanation:
x+x=66
2x=66
x=33
1st number is 33 and 2nd is 27
To determine the length of the hypotenuse, apply Pythagorean theorem.
A^2 + B^2 = C^2
(10)^2 + (24)^2 = C^2
100 + 576 = C^2
676 = C^2
C = 26 cm.
The hypotenuse is 26 cm.
