How did westward expansion impact the tensions between the north and the south?

Expansion lead to economic promise and fueled the manifest destiny but it also lead to sectional tension over slavery. The north contained a lot of abolitionists while the south was commonly pro-slavery, this increased sectional tension because each side wanted to see their ideals extended into the west.

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°
