Answer: 
Step-by-step explanation:
Given: The first term of Geometric series : a=1
The seconds term of Geometric series : 
The common ratio between the terms is given by :-
We know that the sum of infinite geometric series is given by :-
Hence, the sum of the given infinite series =
Answer:
sin x = 3/5
cos y = 3/5
sin x and cos y are equal
Step-by-step explanation:
First we need to find the length of the hypotenuse
We can use the Pythagorean theorem
a^2+ b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 +8^2 = c^2
36+64 = c^2
100 = c^2
Taking the square root
sqrt(100) = sqrt(c^2)
10 = c
The hypotenuse is 10
Since this is a right triangle we can use trig functions
sin x = opp side/ hypotenuse
sin x = 6/10 = 3/5
cos y = adj / hypotenuse
cos y = 6/10 = 3/5
sin x and cos y are equal
i think the answer is the second choice √9+√9=2√9
