Question

in ∆ A B C, if LA=72°and LB=63°, find LC
explain​

Answer 1

Answer:

angle C = 45°

Step-by-step explanation:

By angle sum property of Triangle

angle A + angle B + angle C = 180°

72° + 63° + angle C = 180°

angle C = 180° - 135°

angle C = 45°

Answer 2

Answer:

Let angle A =72⁰ ,

angle B =63⁰ and

angle C = x⁰

From angle sum property

72+63+x=180

135+x=180

x=180‐135

x=45
