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
:)
The answer is 8, because CA and BC are equal
-4x-24=8
So you move the -24 to the other side.
-4x=32
Divide both sides by -4.
x=-8
Answer:
Question 1: 15 cups
20% (pineapple juice) = 3 cups, 100/20=5, 5*3 = 15 cups
Question 2: 20 cups
25% (orange juice) + 5% = 30%
30% (orange juice) = 6 cups, 30/6=5%, 100/5=20
I can't explain the whole thing very clearly, but hope it helped
Answer: The figure drawn by Alan is a rhombus.
Step-by-step explanation:
Given: Allan drew a polygon with 4 sides and 4 angles with two properties:-
- All four sides are equal.
- None of the angles are right angles.
We know that only a rhombus is a flat shape with 4 equal straight sides and 4 angles .All sides have equal length. Its angles need not to be right angle.
Therefore, the figure drawn by Alan is a rhombus.
