x-y=3
5-2=3
Answer:
circumference is given by πd, where d is the diameter of the circle.
This implies, the circumference= 22/7*150m
=3300/7=471.429m
His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.
So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.
Answer:
B=5
Step-by-step explanation:
a2+b2=c2
12squared+b2=13squared
144+b2=169 Subtract by 144 on both sides
b2=25 Find square root of 25
b=5
Your answer would be 4.
= 6 choices and a total of
=10 total
So then 10-6=4
