I am not so sure because i have not studied this yet i am very sorry
Answer:
No solution.
Step-by-step explanation:
So we have the system of equations:
We can solve this by substitution. Substitute the first equation into the second. Thus:
Distribute the right:
Subtract 4y from both sides:
Subtract the right:
As you can see, this statement is not true. In other words, the system of equations have no solution (likely because the lines are parallel).
And we're done!
There could be collinear but need to be on the same plane
5) So for parallelogram ABCD, ∠B ≅ ∠D, and ∠A ≅ ∠C. Further, ∠B and ∠A are supplementary (i.e., their sum is 180°), and ∠D and ∠C are also supplementary.
So, we have that m∠B = m∠D. Therefore,
.
Now, let's substitute for x back into the expression for either ∠B or ∠D to find it's angle measure.
m∠B =
Now, remember that ∠B or ∠D are supplements of ∠A.
So, m∠B + m∠A = 180°.
That means m∠A = 180° – 72° =
108°.
That seems reasonable, because A appears to be an obtuse angle.
6)
m∠BAE + m∠DAE + m∠ABC = 180°
∠ABC ≅ ∠ADC.
m∠ABC =
m∠ADC =
81°.
7)
DC =
