Question 1 is 87 because two smaller angles added together equals the bigger angle.
question 2 is x=8. the equation is 3x-4+6x+2=70 and then solve for x.
question 3 is x=7. the equation is 6x-2+15=7x+6 and then solve for x.
question 4 is 21 because an angle bisector splits and angle into two equivalent angles.
question 5 is x=7. the equation would be 62=2(4x+3) and then solve for x.

I guess this could be personal prefrence, but I think that most people would live near the Tropic of Capricorn because the Arctic Circle would way to cold to habit and live there all year.
They carry warm, equatorial waters and winds to the western coasts of continents, especially in the southern hemisphere because of the large oceanic expanse there
