Which country used the scorched earth policy?

When Germany attacked the Soviet Union in June 1941, a lot of district governments took the first step to begin a partial scorched-earth policy to deny the invaders access to electrical, telecommunications, rail, and industrial resources.

Explanation:

Germany

the correct answer is political prisoners

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°
