Answer:
5
Step-by-step explanation:
3/5 × 5
Divide through by 5
And you're left with 5
Lets take it in order:
1) 90 deg because the angle right next to it is a right angle
2) 128 deg becasue of the angle directly across from it
3) x = 180 - 128 = 52 deg
4) 180 = 90 + 52 + x so x = 180 - 90 - 52 = 38
5) 180 = 38 + x so x = 180 - 38 = 142
6) Same as 4
7) Same as 5
Check my math, as I just did it in my head
A I think I don’t know cause the formula is y=Mx+b is a slope formula so he have to be right
