How did life change for surviving peasants and serfs after the plague? a. they began to demand wages for their labor. b. they moved from towns to the country. c. they had to work much longer days. d. they took over the manors.

The correct answer is - a. They began to demand wages for their labor.

After the plague ended, the countries affected by it were in a very bad position because they lost millions of people because of it. That led to a very big deficit of laborers. The laborers peasants and serfs that survived found themselves in a situation where there was work in abundance, so much so that they were not even able to work on all farmlands. Because of that, they started to demand higher wages for their labor, and since the large land owners were lacking laborers and started competing for the ones that remained, the peasants and serfs started to get much more money for their work.

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°

i think it would be a
