After the french revolution which political symbols were included in the clothing in france and why

It was the French Tricolor.  The colors of red, white and blue became the new colors of the French flag. It was worn by the French to show their support for the Revolution’s ideals and as a symbol of patriotism.

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°
