When added, these two angles are supplementary, meaning that their sum is 180. This means that we can do the following to find x, and eventually DBC:
3x+67+4x+50=180
Simplifies to:
7x+117=180
Then by the Subtraction Prop. of Equality:
7x=63
Then divide by 7 on both sides to get that x=9.
We then substitute 9 into angle DBC.
4(9)+50
=36+50
DBC=86

Answer:
Step-by-step explanation:
Area of a rectangle is base times height
6 thousand less than 37,215
6000 less than 37,215 is basically subtracting.
37,215 - 6000 = 31,215
The one that makes most sense is the last one, but I would define it as "Two times some number divided by 4".
