Answer:
130
Step-by-step explanation:
The two angles add up to 180 since they form a straight line
4y-50 + 3y+55 = 180
Combine like terms
7y +5 = 180
Subtract 5 from each side
7y-5+5 = 180-5
7y = 175
Divide each side by 7
7y/7 =175/7
y =25
The obtuse angle is greater than 90 degrees
3y+55
3(25) +55
75+ 55
130
