Explanation:

The war of Independence of the United States was a warlike conflict that faced the Thirteen original British Colonies in North America against the Kingdom of Great Britain. It happened between 1775 and 1783, ending with the British defeat at the Battle of Yorktown and the signing of the Treaty of Paris

The immediate cause of this conflict was the unjust treatment that Great Britain inflicted on the settlers, because they contributed wealth and taxes to the metropolis but did not have the means to decide on such taxes, so they felt marginalized and not represented.

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°
