Answer:
D
Step-by-step explanation:
Because the angle with measure 29 degrees and n are a linear pair, their value must add up to 180 degrees. Therefore:
n+29=180
n=180-29
n=151 degrees, or answer choice D
Hope this helps!
Answer:

Step-by-step explanation:
Answer: I think you meant (9^3) 6
If I’m not mistaken the answer is
4374 because 9x9x9= 729x6
A. Given (This is part of the original problem)
b. Supplementary angles form 180 degrees (The definition of supplementary angles is that two or more angles have a sum of 180 degrees. DC is a straight line and has a measure of 180 degrees)
c. Substitution (Given the two previous statements, they are each equal to 180 degrees. Since 180=180 then you can substitute the angles in the equation.)
d. Subtraction (m<2 is being subtracted)
e. Subtraction postulate (Since the same quantity was being subtracted from each side of the equation, they are still equal)
