It takes 24 feet of fence to surround a square piece of land in linda’s backyard. linda wants to plant flowers everywhere but on the diagonal sidewalk. there is 1 foot of sidewalk along two sides of the square. what is the area of the sidewalk? (a) 5 ft2 (b) 5.5 ft2 (c) 6 ft2 (d) 6.5 ft2 (e) 7 ft2

Step-by-step explanation:

First of all, the equation of the circle is

Where the radius is 17 units long.

Now, we need to find the slope of the radius OP,

Then, we use the perpendicular rule

Next, we use the point-slope formula, with the slope we found and the point (8,15).

Therefore, the equation of the tangent line is
