We can find the right angle of the triangle by finding the slope of the sides .
Any right angle makes an angle of 90 degrees and the lines are perpendicular .
For perpendicular lines product of slopes is -1.
In other words the slopes have opposite signs and are reciprocal .
Let us find the slopes of AB,BC,CA.
Slope of two points can be found by the difference in y values divided by different in x values
Slope of AB=
Slope of BC=
Slope of CA=
The slopes of AB and CA are reciprocal of each other with opposite signs or we can say their product is -1 so they are perpendicular.
Angle A is the common angle to these sides so we say angle A is the right angle
For each friend, there will be 2 numbers of peanuts.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Sandra has 18 bags of peanuts to hand out to 9 friends. The number of the peanuts bag will be calculated as,
Number = 18 / 9
Number = 2 bags
Therefore, the for each friend, there will be 2 numbers of peanuts.

Answer: 4.5 feet he can buy if he has $11.25
Step-by-step explanation:
Since we have given that
Cost of candy per foot = $2.50
Total money he spent on candy = $11.25
Let the number of feet he can bought be x
Now, According to question, we get that ,
So, 4.5 feet he can buy if he has $11.25.
