-3 (2a-9b+5c)
common factor out the lowest common factor which is -3
Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that
. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have
. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides
as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.
