The radius is 2 yards...
Formula for circumference is
so divide your circumference by 3.14 or pi and you get 4 the square root of 4 is 2.
Hope this helps!
Answer in fraction form: -17/4 < x < 11/4
Answer in decimal form: -4.25 < x < 2.75
=======================================================
Work Shown:
|4x+3| - 9 < 5
|4x+3| < 5+9 .... adding 9 to both sides
|4x+3| < 14
-14 < 4x+3 < 14 .... see note at the bottom
-14-3 < 4x < 14-3 .... subtracting 3 from all sides
-17 < 4x < 11
-17/4 < x < 11/4 .... divide all sides by 4
-4.25 < x < 2.75
This says that x is between -4.25 and 2.75, but x is not equal to either endpoint.
Note: I used the rule that |x| < k becomes -k < x < k where k is a positive real number.
100 because opposite angles are equal. The angles in the triangle above add up to 80 so the last angle must equal 100. Since angle 1 is directly opposite to that angle, it also equals 100.
The 2nd one or either the last one, I suggest the last one hope this helps!!
