Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find the measure of angle CQJ
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite.
substitute the values
Part 2) Find the measure of angle LIJ
step 1
Find the measure of angle IJL
we know that
The inscribed angle is half that of the arc it comprises.
substitute the values
step 2
Find the measure of angle ILJ
we know that
The measurement of the external angle is the semi-difference of the arcs it encompasses.
substitute the values
step 3
Find the measure of angle LIJ
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
In the triangle LIJ
substitute the values
<span>The radius of a sphere join refers to the (D) the center and a point on the sphere. A radius is the distance of the center point to any sides of the circle or sphere. The point on the sphere can be anywhere. The center and a point on the sphere forms a sphere join.</span>
Answer:
5 hours
Step-by-step explanation:
Answer: A(x) = 15 ft + 2x
EXPLANATION
Given,
The dimension of the rectangular garden is 20 ft by 15 ft.
Dimension of a rectangle is written as Length by Width
This implies that,
Length of the garden = 20 ft
Width of the garden = 15 ft
The garden has a walk around it of width x.
The combined width of the garden = Width of garden + 2x
[we are adding twice the width of the walk because it is
around the garden (this means it will add to the width of the garden on both the left and right sides)]
Combined width of the garden, A(x) = Width of garden + 2x
Since width of the garden = 15 ft
A(x) = 15 ft + 2x
