100÷11=9.09090909
converting it it will be 9.1 miles per hour
I believe that is ten right?
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 .
Answer:
105
Step-by-step explanation:
55+50+x=180
x=75 this is the other inside angle. to find b, you need to take 75 and subtract it from 180. this is because a straight line is equal to 180 degrees
