Answer:
y = (4/5)x - 3
Step-by-step explanation:
slope intercept form: y = mx + b
Note the equal sign, what you do to one side, you do to the other. First, subtract 4x from both sides:
4x - 5y = 15
4x (-4x) - 5y = 15 (-4x)
-5y = -4x + 15
Next, divide -5 from both sides:
(-5y)/-5 = (-4x + 15)/-5
y = (-4x + 15)/-5
Simplify Divide -5 from all terms within the parenthesis:
y = (4/5)x - 3
y = (4/5)x - 3 is your answer.

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

Thats it.....
Do you need something else or just that?
