Answer:
107 degrees
Explanation:
The lines intersect to create a triangle. The sum of the interior angles of a triangle is 180 degrees.
a + b+ c = 180
We deduce the unlabeled angle (in the lower right corner) by considering the line that goes from that angle to the a angle on the left side. The line itself has a 180 degree angle (on each side). And we know the exterior angle is 107 degrees... that leaves 73 for the interior angle.
We take the equation above again... by putting now the value of C (the un-named angle):
a + b + 73 = 180
We isolate the a+b part... to get a+b = 107, the same value as the exterior angle.

Explanation:
When an element tends to lose its valence electrons in chemical reactions, it behaves more like a metal.
When an element tends to gain valence electrons in chemical reactions, it behaves more like a nonmetal.
Metalloids have properties intermediate between those of pure metals and pure nonmetals. Usually, metalloids appear in groups where they are sandwiched between nonmetals and metals such as in groups 13, 14 and 15.

Answer:
54 dollars
Explanation:
Because this problem involves simple interest, and the money is only deposited for one year, you can calculate the amount of money in the bank after one year by thinking about a percent increase. Johnny starts with 50 dollars in his bank account, and we are given that he will experience an 8% increase over the year. This means that the amount of money in his bank account after one year is just 50 + 0.08*50 (the principal amount plus the simple interest, or amount of money that increases during the year). This is equal to 50 + 4, or 54 dollars.
Note that, whenever we are dealing with simple interest, the amount of money in the bank after a certain number of years is just P(1 + PRT), where P is the principal amount, R is the interest rate, and T is the number of years the money is in the bank.
