Answer:
70 degrees
Step-by-step explanation:
180-120=60
180-(60+50)=70
The other integer is 289. To solve first make the equation:
x+y=286
Then you can plug in -3 into one of the variables (it doesn't matter which one you choose)
x-3=286
Then solve for x by adding 3 to both sides of the equation getting you 289
