What effect did the Industrial Revolution have on families?

People moved to the cities for factory jobs.
People moved south to pick cotton on farms.
Women kept house rather than working on farms.
People moved closer to ports to find work on ships.

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°

studies show tha in 7.5 billion years from now, the expanding sun will engulf, and destroy, the earth.
