Janice is buying paint to paint her new apartment. The store sells paint in one-gallon cans. How accurate does her estimate need to be for the amount of paint needed?

∠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°

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
