Question

If two angles of a triangle ABC are ZABC = 850, ZBCA = 200. Then what will be the third angle of the triangle is:​

Answer 1

Answer:

Third ∠= 75°

Step-by-step explanation:

∠ABC+ ∠BCA+ ∠BAC=180° [Anglesum property]

85°+20°+ ∠BAC=180°

∠BAC= 180°-(85°+20°)

         = 180° - 105°

         = 75°
