Question

In △ABC , ∠A =30° , ∠B =45°, .Find angle ∠C. ​

Answer 1

ANSWER:

∠C = 105°

SOLUTION:

∠A + ∠B + ∠C = 180°

(Angle sum property)

30° + 45° + ∠C = 180°

75° + ∠C = 180°

∠C = 75° - 180°

∠C = 105°

Answer 2

Sum of all three angles of a triangle = 180°

angle A + angle B + angle C = 180°

30° + 45° + angle C = 180°

75 ° + angle C = 180°

angle C = 180° - 75°

= 105°

angle C = 105° Answer
