Step-by-step explanation:

b + 35° = 180° ( supplementary angle )

b = 180° - 35°

b = 145°

Answer: [tex]\Large\boxed{b=145^\circ}[/tex]

Step-by-step explanation:

Given information

∡1 = 35°

∡b = ?

Total Angle = 180° (Supplementary Angle)

Derived formula from the given information

∡1 + ∡b = Total Angle

Substitute values into the given formula

(35) + b = 180

Subtract 35 on both sides

35 + b - 35 = 180 - 35

[tex]\Large\boxed{b=145^\circ}[/tex]

Hope this helps!! :)
