8) x = 4°

9) $7176.53

10) 22

Step-by-step explanation:

8) The sum of all three interior angles of any triangle = 180°

11x + 25x + 9x = 180°

45x = 180°

divide both sides of the equation by 45:

x = 4°

9) ($6500 x 1.02) = 6630 x 1.02 = 6762.60 x1.02 = 6897.85 x 1.02 = 7035.81 x 1.02 = 7176.53
