​

Answer 1

Question:-

• If ∠DBC= 70⁰ and ∠DCB= 35⁰ . Find ∠BAC 

Answer: -

• ∠BAC = 75⁰

Given:-

• ∠DBC= 70⁰
• ∠DCB= 35⁰

Solution:-

We already know sum of all angles of triangle is 180⁰.

So,

∠DBC + ∠DCB + ∠BAC = 180⁰

70⁰ + 35⁰ + ∠BAC = 180⁰

115⁰ + ∠BAC = 180⁰

∠BAC = 180⁰ - 115⁰

∠BAC = 75⁰

Therefore , ∠BAC = 75⁰.
