Answer:
Supplementary Angles
Adjacent Angles
Step-by-step explanation:
Angles 1 and 2 share a vertex and form a straight line. These angles are called supplementary angles. They add to 180 degrees and form a straight line. They are adjacent as well because they share a vertex and side.
the answer is D i added then subtracted

x=12
Step-by-step explanation:
6/3=x/6
36=3x
x=12
Answer:
Step-by-step explanation:
The addition of angles ABD and DBC make up the larger angle ABC. We know that angle ABD = 65 and DBC = 60, therefore
angle ABC = 65 + 60 and
angle ABC = 125 degrees
