Answer:
Regular proof is a method of proving the statement directly. In this method, we just proved it by using direct formula or theorem. whereas, Indirect proof is a way of proving by contradiction
Step-by-step explanation:
R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
8920000000.
Since the problem is asking for a positive 10^9 power, the final number with be greater than 8.92
Answer: Linear pairs of angles add up to 180 degrees. A+B=180
Step-by-step explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees
