Question

Angle a + angle b equal to 65 degrees angle b + angle c equal to 140 degrees then find angle b

Answer 1

Answer:

25°

Step-by-step explanation: ∠a+∠b=65°

∠b+∠c=140°

∠a+∠b+∠c=180°           (sum of all angles of a triangle)

∠a+140°=180°               (∠b+∠c=140°)

∠a=40°

40°+∠b=65°                  (∠a+∠b=65°)

∠b=25°
