Similar to the other question, because AB is parallel to CD, you know the 72º angle corresponds to the angle on top of y.
Because that angle above y and y together make a straight line (and a straight line measures 180º), you have
72 + y = 180
Solving that for y, you get y = 108º
Answer:
I believe it is 4.8
Step-by-step explanation:
2689
rounded to the nearest tens = 2690
rounded to the nearest hundreds = 2700
rounded to the nearest thousands = 3000
If the number before the place it needs to be round off is 5 and above, then it is rounded up. If the number is 4 and below, it is rounded down.
For example:
2444
rounded to the nearest tens = 2440
rounded to the nearest hundreds = 2400
rounded to the nearest thousands = 2000
