ANSWER

EXPLANATION
The equation of the given line is

This line is in the slope -intercept form,

where

is the slope.
The line which is parallel to this line and passes through (1,11) also has slope

Let the equation of this line be

This implies

We substitute x=1 and y=11 to get


The required equation is

Answer:
One leg - 15 inches
Second leg - 36 inches.
Step-by-step explanation:
One leg - x inches.
Second leg - (x + 21) inches.
Hypotenuse - 39 inches.
Using Pythagorean theorem
x² + (x + 21)² = 39²
x² + x² + 2*21x + 21² = 39²
2x² + 42x - 39² + 21² = 0
2x² + 42x - 1080 = 0
x² + 21x - 540 = 0
(x - 15)(x + 36) = 0
x = 15, x = - 36
We can use only positive value.
One leg - x inches = 15 inches
Second leg - (x + 21) inches = 15+21=36 inches.
The answer to this equation is 48.
