Large areas of Texas have a dry climate that is not good for many types of farming. For this reason, many people raise livestock like cattle. The cattle industry in Texas boomed after the Civil War, and some Texas cities were able to grow because of their location on the cattle trails. Which two cities were known for their location first on the cattle trails and then as hubs for the railroads? A) Austin and El Paso

B) Waco and Fort Worth

C) Houston and Galveston

D) Laredo and Corpus Christi

D

Explanation:

I just took the test hope this helps :)

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°

i think the answer is the one about environmental and social health.

hope this
