Step-by-step explanation:
Given is an equation in xy as xy =12
WE are to complete the coordinate table for xy =12
Let us give different values for x and find corresponding values of y
Note that x or y cannot equal 0 in this
So let us give other values
x y
12 1
6 2
4 3
3 4
2 6
1 12
-1 -12
-2 -6
-3 -4
-4 -3
-5 -2.4
-6 -2
-12 -1
Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given by:
A = lw.
In this problem:
- She has enough tiles to cover 324 square feet, hence A = 324.
- She wants the length of the patio to be 15 feet longer than the width, hence l = 15 + w.
Thus:
324 = w(15 + w)
w^2 + 15w - 324 = 0
w = -27 or w = 12.
We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.
The dimensions should be a width of 12 feet and a length of 27 feet.

Answer
Step-by-step explanation:
chord makes or arc make 120° at the center.
sum of other two angles of triangle=180-120=60
because they are equal.
so each angle=60/2=30°
tangent line makes angle 90° with radius .
so 30+y=90
y=90-30=60°
