I really dont understand what to do here if you can please help
NNADVOKAT [17]

Answer:

see below

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

5x+60   + 3x-40 = 180

Combine like terms

8x +20 = 180

Subtract 20 from each side

8x+20-20=180-20

8x= 160

Divide by 8

8x/8=160/8

x=20

5x+60 = 5*20+60 = 160

3x-40 = 3*20-40 = 20
