Answer:
k = 10
Step-by-step explanation:
The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.
So 10k + 15 must equal the remaining 115
subtract 15 from each side and you get 10k = 100
divide each each by 10 and you get the answer of k = 10
You should plug this into a graphing calculator on your computer! It helps a lot!

Answer: 4 = n
Step-by-step explanation:
5n + 34 = -2(1-7n)
Distribute negative 2 to both 1 and negative 7n. You do this first due to the rules of PEMDAS
5n + 34 = -2 + 14n
Add two to both sides of the equation in order to further isolate (n) in 14.
5n + 36 = 14n
Subtract 5n from both sides of the equation so that the values with (n) are on one side of the equation.
36 = 9n
Divide nine from 36 and 9n in order to isolate (n).
4 = n
This then gives you your final answer.
