Answer:
75 degrees
Step-by-step explanation:
60 = 45= 75 = 180
Because every triangle has 180 degrees in it
Answer:
The required expression is: 
Step-by-step explanation:
Given



Required
Write an expression for this scenario
If 1 pound of blueberry cost $2.50
then b pounds = 2.50 * b
If 1 pound of apple cost $2
then a pounds = 2 * a
The required expression (y) is then calculated as



Hence, the required expression is: 
The circumference of the outer edge of the path around the pool is 113.04 ft.
<h3>
What is the circumference?</h3>
The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle.
Given
A circular swimming pool has a radius of 15 ft.
There is a path all the way around that pool that is three feet wide.
A circle has a radius of 15 feet.
A larger circle goes around the smaller circle that is 3 feet wide.
The radius of the outer edge of the path around the pool = Radius of circle + width of outer circle.
The radius of the outer edge of the path around the pool = 15 + 3
The radius of the outer edge of the path around the pool = 18ft
The circumference of the outer edge of the path around the pool is;

Hence, the circumference of the outer edge of the path around the pool is 113.04 ft.

Perimeter is a continuous line forming the boundary of a closed geometrical figure. perimeter of a pentagon = AB+BC+CD+DE+EA (that is 5 sided figure)
so my plan is easy but effective, calculate all those distances using those coordinates with the aid of distance formular. then you add those distances algebraically .
