This is the concept of trigonometry and its identities;
We are required to calculate the length of the kite's diagonals;
Here we use the trigonometric identities;
let theta=x
tan x=opposite/adjacent
opposite=17
adjacent=10
thus
tan x=17/10
x=tan^-1 17/10
x=59.54
Therefore half the length of the diagonal will be given by:
sin x=h/10
h=10 sin x
h=10 sin 59.54
h=8.62
thus the length of the diagonal will be:
2*8.62
=17.24 in
