British action during world war 1

It was crazy watch 1917 to learn more

Explanation:

Great Britain entered World War I on 4 August 1914 when the king declared war after the expiration of an ultimatum to Germany. The official explanation focused on protecting Belgian neutrality; the main reason, however, was to prevent a French defeat that would have left Germany in control of Western Europe.

the main reason, however, was to prevent a French defeat that would have left Germany in control of Western Europe.

Explanation:

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 would go with the last one
