I believe it's both a and b
34 is a even number and it's not divisible by 4. So the answer is No.
We know, a number is divisible by 9 if the sum of digits is also divisible by 9.
Also, since A is an digit, so A is in between 0 to 9.
2+A+5+A+0+A+2 = 3A + 9
3A + 9 should be divisible by 9.
3A + 9 = 9n
A = (9n -9)/3
For n= 1 :
A = 0
For n=2 :
A = 3
For n= 3 :
A = 9
After this A > 9 which is not accepted.
Therefore, the digit A can be 0, 3 and 9 .
Hence, this is the required solution.
Answer:
20 sides
Step-by-step explanation:
The formula that relates interior angles with number of sides is:
Where
n is the number of sides.
We know each interior is 162 degrees, so we substitute and cross multiply and solve for n:
THus, the polygon has 20 sides
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=132,−118
