I think it's the 2 one I'm 76 percent sure
Answer:

Step-by-step explanation:
Let the number be
.
Then,

This implies that;

We multiply both sides by
to obtain;



Or

let
(hypotenuse ) c = 10 in
(perpendicular) a = 8 in
(base) b =?
By using Pythagoras theorem
c^2= a^2+b^2
(10)^2 = (8)^2 +(b)^2
100 = 64 +(b)^2
100- 64 = (b)^2
36 = (b)^2
√36 = b
6 = b
hence b= 6 in
What that is exactly??? I want to help but I can’t! Tell me tell me
