The two angles form a straight line which is equal to 180 degrees. This makes the angles supplemtary.
To find x, add the two angles together to equal 180:
7x + x+20 = 180
Combine like terms:
8x + 20 = 180
Subtract 20 from both sides:
8x = 160
Divide both sides by 8:
X = 20
Answer:
b = 36
Step-by-step explanation:
27 divided by 6 = 4.5
45 divided by 10 = 4.5
- so, each point was multiplied by 4.5
8 times 4.5 = 36
Answer:
C
Step-by-step explanation:
<h3>
Answer is ED</h3>
note: ED is the same as DE. The order of the segment letters does not matter.
============================================
Explanation:
In the sequence ABC, the letter B is the second letter and A is the first.
So the corresponding segment to BA will have its first slot be the second letter of DEF, and its second slot be the first letter of DEF. That's how I'm getting ED for the answer. It is the same as DE because it's the same segment.
The corresponding sides are congruent due to the CPCTC which stands for "corresponding parts of congruent triangles are congruent".
