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
