Answer:
177
Step-by-step explanation:
8.7×5×2=87

An outside angle is equal to the sun of the two opposite inside angles.
The given inside angle is 75, the angle next to it is also 75 ( because there is a single line through the red arc, this means the angles are identical).
W = 75 + 75
W = 150 degrees.
