The British were more hunger for the lands and the native Americans distrust the British. The French were more interested in further trading with native american people. The French traders  also married the native American women and their missionaries converted many people of Native America into Catholicism.

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°

more than 65,000 union soldiers had been killed that summer.

more than 65, is the correct
