Answer:

The false statement is: They must occur under carefully controlled conditions found in a laboratory.

Step-by-step explanation:

Scientific experiments do not always occur in laboratories, also, in the case of social studies, the experiments are done under not controlled conditions to prove the hypothesis.

On the other hand, all scientific experiments must be well documented and they always give useful results (in case the hypothesis is rejected, future investigations will use other hypothesis).

Answer:

m∠X = 29°

m∠V = 61°

m∠W == 90°⇒given

Step-by-step explanation:

∵ ΔXWV is right angle at W

∴ m∠W = 90°

∴ m∠X + m∠V = 180° - 90° = 90°

∵ m∠X = 2x + 5 and m∠V = 4x +13

∴ 2x + 5 +4x + 13 = 90

∴ 6x + 18 = 90

∴ 6x = 90 - 18 =72

∴ x = 72/6 = 12

∴ m∠X = 2(12) + 5 = 29°

∴ m∠V = 4(12) + 13 = 61°
