What was one negative effect on the growth of cities in the late 1800s?

The growth of concentrated poverty

Explanation: With large amounts of people in close quarters, poverty became a problem as jobs were not available for all of the people.

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°

-an amendment is proposed.

-two-thirds of congress must approve.

-thee-quarters of states must approve.

-the proposed amendment becomes law.
