Answer:
15.39 degrees
17. I got 19 degrees for x
Explanation:
17.
2x+2x= 76
4x=76
devide 4x and 76 by four and you would get 19
4(19)=76
4x19=76
15: 39 degrees
17: 26 degrees
15. straight line=180 degrees
51+90+c=180
141+c=180
c=180-141
c=39 degrees
17.straight line=180 degrees
2x+2x+76=180 degrees
4x+76=180
4x=180-76
4x=104
x=26
