Question

in angle abc if la = 62degree and lb= 78degree find lc​

Answer 1

Answer:

lc = 40°

Step-by-step explanation:

Let lc be x

Let lc be xla = 62°

Let lc be xla = 62° lb = 78°

Let lc be xla = 62° lb = 78°According to question,

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180°

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180° la + lb + x = 180°

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180° la + lb + x = 180° 62° + 78° + x = 180°

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180° la + lb + x = 180° 62° + 78° + x = 180° 140° + x = 180°

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180° la + lb + x = 180° 62° + 78° + x = 180° 140° + x = 180° x = 180° - 140°

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180° la + lb + x = 180° 62° + 78° + x = 180° 140° + x = 180° x = 180° - 140° x = 40°

Let lc be xla = 62° lb = 78°According to question, We know that, Sum of all angles = 180° la + lb + x = 180° 62° + 78° + x = 180° 140° + x = 180° x = 180° - 140° x = 40° So, lc = 40°
