Answer:

y = 115°

Step-by-step explanation:

We Know That

Sum of all the angles = 360°

Let the other three angles, w, x and z.

Angle w = 110°

Angle x = 80°

Angle y = ?

Angle z = 55°

w + x + y + z = 360°

110° + 80° + y + 55° = 360°

245° + y = 360°

y = 360° - 245°

y = 115°

Hence, angle y = 115°
