Rodrigo has a cherry fruit-by-the-foot snack that is 36 inches long. if he eats 7.2 inches of the snack , and then gives 4.25 inches to sergio , how many inches will be left ?

Cherry Fruit-by-the-foot snack left is 24.55 inches

Solution:

Total length of the cherry Fruit-by-the-foot snack is 36 inches

Part of the cherry Fruit-by-the-foot snack eaten by Rodrigo is 7.2 inches

Part of the cherry Fruit-by-the-foot snack given to the Sergio is 4.25 inches

part left of cherry Fruit-by-the-foot snack = Total –  (Part of the cherry Fruit-by-the-foot snack eaten by Rodrigo +  Part of the cherry Fruit-by-the-foot snack eaten by Rodrigo)

Total = 36 - (7.2 + 4.25) inches

= 36 – 11.45 inches  = 24.55 inches

Cherry Fruit-by-the-foot snack left is 24.55 inches

∠2 = 52°

Step-by-step explanation:

Since 1 angle = 90° then the sum of the other 2 angles = 90°, that is

∠2 + ∠3 = 90 ← substitute values

3x + 1 + 2x + 4 = 90

5x + 5 = 90 ( subtract 5 from both sides )

5x = 85 ( divide both sides by 5 )

x = 17

Hence

∠2 = 3x + 1 = (3 × 17) + 1 = 51 + 1 = 52°
