Hi! so you would find x by adding the corners up to 180 degrees.
steps:
Add the corners
90+(2x+1)+(5x+5)
7x+96=180
then subtract 96 from 180
you’d get 7x = 84
then divide 7 on both sides and get x=12
Answer:
Its 40 degrees
Step-by-step explanation:
60+80=140
180-140=40 (a straight line is always 180 degrees)
Hope it helped
