Answer:
x=80 degree
Step-by-step explanation:
(x-5)+(x-6)+(2x-7)+x+(2x-2)=540 degree (sum of interior angles of a pentagon)
x-5+x-6+2x-7+x+2x-2=540
7x-20=540
7x=540+20
x=560/7
x=80 degree
Combine like terms.
5c = 45
Divide 5 on both sides.
c = 9
Hope this helps!
Plug the numbers into the equation
5(5) - 2 = ?
25 -2 = 23
23
One example is when n is 11. 11^2 + 4 = 125. 11 is odd but the 11th term of the sequence, 125, is not prime because 125 is divisible by 5 and 25.
