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:
46 m
Step-by-step explanation:
The perimeter of any figure is the sum of the lengths of its sides.
8m +10m +10m +18m = 46 m
The perimeter of the figure is 46 meters.
Answer:
=x2y−2xy2+7y2z
Step-by-step explanation:
Simplify
Let's simplify step-by-step.
4x2y+3y2z−2xy2−3x2y+4y2z
=4x2y+3y2z+−2xy2+−3x2y+4y2z
Combine Like Terms:
=4x2y+3y2z+−2xy2+−3x2y+4y2z
=(4x2y+−3x2y)+(−2xy2)+(3y2z+4y2z)
=x2y+−2xy2+7y2z
Answer:
=x2y−2xy2+7y2z
Answer:
