Assuming we have parallel lines, we can solve for x.
Since a = 3x - 10 (vertically opposite angles are equal),
3x - 10 = 2x + 15 (alternate angles are equal)
x = 25
Hence, angle a = 3(25) - 10 = 65°
You have to divide negative fifty-six by eight to get the charge on each particle. So you do -56/8. Which gives you negative seven as the answer.
Answer = -7
2. an=20+an−1 and a1=145
she starts with 145 so a1=145 and then adds 20 every month: an=20+an−1
12*3=36 pounds. so therefore 36
