115 degrees because there are 180 degrees in a triangle so let the missing angle in the trinagle be x. Then we have x+75+40=180. Solving for x and subtracting that from 180 (supplementary angles) we get 115 degrees.
Answer:
A) 5x-6y=3
B) 7y=2x+8
B) -2x + 7y = 8 then multiplying "B" by 2.5
B) -5x +17.5y = 20 then adding this to A
A) 5x -6y = 3
11.5y = 23
y = 2
x = 3

Answer:
x>5 so any number greater than 5 will work
Step-by-step explanation:
6x-8>22
move -8 to the other side so addition cuz it's a negative number
6x>30
now divide the 6x by 6 and 30
so now it will be
x>5
