Respuesta :

The two angles given are vertical angles which mean they are the same.

x +40 = 60

Subtract 40 from both sides:

x = 20

Answer:

x=20

Step-by-step explanation:

These are verticle angles, meaning the two should equal one another. If one angle is 60, its vertical angle is x+40.

x+40=60

x=20 (subtract 40 from both sides)
