32/4= ? = 8
Answer:

Step-by-step explanation:

Open up the parentheses

-7x cancels out on both sides

-12 cancels out on both sides

I hope this helps!
Answer:
Step-by-step explanation:
x + 32 + 2 vertically opposite degrees = 180 Beginning condition
x + 32 + x + 126 + 36 = 180 Combine like terms
2x + 194 = 180 Subtract 162 from both sides
2x = -14
x = -7
========
So the three angles are
36
-7 + 32 = 25
-7 + 126 = 119
Total = 180
That negative can throw you for a loop.
Answer:
B
Step-by-step explanation:
<DCE = BCA (vertical angles are congruent)
DC corresponds to CB,
DC/CB = 15/5 = 3
EC corresponds to CA,
EC/CA = 12/4 = 3
Thus, two sides in ∆ABC are proportional to two corresponding sides in ∆EDC, and also, the included angle in ∆ABC and ∆EDC are congruent to each other. Therefore, based on the SAS Similarity Theorem, ∆ABC and ∆EDC are similar.
