Properties of triangle​

Answer 1

Given:-

• ∠A = 60° , 35°

⠀

To find:-

• ∠n and ∠m.

⠀

Solution:-

Firstly,

• finding the ∠m.

⠀

→ ∠m = 35° (Because opposite angles of equal sides are equal)

⠀

Now,

• finding the ∠n.

⠀

→ ∠BAC = 60° + 35°

→ ∠BAC = 95°

→ ∠ACB = n

→ ∠ABC + ∠BAC + ∠ACB = 180°

→ n + 95° + 35° = 180°

→ n + 130° = 180°

→ n = 180° - 130°

→ n = 50°

⠀

Hence,

• the ∠n = 50°
• ∠m = 35°
