------------------

Question: In triangle abc angle a = 60 angle b =75 then find angle c

------------------

Points to know before answering this question.

• The total sum of all angles in a triangle is 180°

------------------

In Δ ABC,

∠A = 60°

∠B = 75°

∠C = ?

In a Δgle, the sum of all three angles is equal to 180°

∴ By ASP of a triangle,

∠A + B + ∠C = 180°

60° + 75° + ∠C = 180°

135° + ∠C = 180°

         ∠C = 180° - 135°

         ∠C = 45°

--------------------------------------------------

Not sure with the answer?

There is a cool method to check out whether the angles you have found are correct. If you add all the angles you obtained, you must get 180, if you do the answer is correct. If you dont the answer is wrong. Lets check whether the answer I've obtained is correct.

(this step IS NOT required in the answer, just for checking purposes)

∠A + ∠B + ∠C

60° + 75° + 45°

180°

Therefore, our answer is correct!
