I am pretty sure the answer would be 80 because angle D wold equal the exact same thing as angle B so C+A equals 100. And a triangle equals 180 so 180-100= angle B.

Answer:

Find the minimum number of gallons she'll need for a trip that is $200$ miles

$\frac{1}{18}\frac{gallon}{miles} =\frac{x}{200}\frac{gallon}{miles}\\ \\x=200/18\\ \\x= 11.11\ gallons$

The sum of three consecutive natural numbers is 1146, find the numbers.

-BARSIC- [3]

$\text{Let the 3 consecutive numbers be}~ x,~x+1~ \text{and} ~x+2.\\\\\text{According to the condition,}\\\\x+x+1+x+2 = 1146\\\\\implies 3x +3 = 1146\\\\\implies 3(x+1) = 1146\\\\\implies x+1 = \dfrac{1146}3 = 382\\\\\implies x= 382-1 = 381\\\\\text{Now, the numbers are}~ 381,~382~\text{and}~383$
