Why was britain concerned about france's defeat by germany at the end of the 19th century?

a. britain lost the economic support of the french government
b. britain had wanted to attack france as well
c. british people thought they also might be attacked by the germans
d. british people felt sorry for the former french king and his family

The correct answer is option "C".

Although Great Britain might have had the greatest navy in the world during the 19th century, the British felt unprepared for an armed German invasion, especially after Germany's victory in the Franco-Prussian War (1870-1871). For that reason, Britain was concerned about France's defeat by Germany at the end of the 19th century, since British people thought they also might be attacked by the Germans. Germany was now seen as the Britain's potential new enemy because of its efficient as well as militaristic power.

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°
