This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300
In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2
Answer: 4
Step-by-step explanation:
so you basically make the + sign into a - sign as when there is a + and - sign next to each other it will always change into a - sign so once you do that it will look like this
11+(-7)
11-7

Answer:
∠ ABC = 60°
Step-by-step explanation:
the measure of an inscribed angle is hal the measure of its intercepted arc.
∠ ABC = 
AC = × 120° = 60°
The answer is C! The measure of central angle is 2x the measure an inscribed angle!
