Answer:
-18
Step-by-step explanation:
By opposite, I believe this is talking about the sign. Note that taking an absolute value of a number always results in a positive number.
|-18| = 18
The angles are adjacent and supplementary. Adjacent angles share a vertex and a side. Supplementary angles are angles whose measure add up to 180. The measure of a straight line is 180, and angle 1 and 2 fall on the same side of a line, so their measures add up to 180.
Answer:
Step 3
Step-by-step explanation:
They didn't subtract the 1 on the right side making it equivalent
Answers:
Common angles: ΔBGC and ΔGDC
Common sides: ΔGE and ΔAG
A common angle is a triangle that exists in two or both of the triangles.
Here, the common angles should be ΔBGC and ΔGDC.
These two angles are triangles, and they consist in both triangles.
A common side is when two angles have one vertex in the same area.
Here, we see that the common sides are ΔGE, because they intersect.
Another common side we see here is ΔAG, because they also intersect.
Hope this answer helps you!
