Question

in the following figure of triangle abc angle abc = 70°and angle ACB=60°. find angle ABD and angle ACE.​

Answer 1

angle ABD is 180-70=110°

angle ACE is 180-60=120°

Answer 2

Answer:

∠ACE = 120°

∠ABD = 110°

Step-by-step explanation:

Given that :-

∠ abc = 70°

∠ACB - 60°

To find :-

∠ ABD = ?

∠ ACE = ?

Solution:-

since straight line = 180

∠abc = 70° and ∠ACB = 60°

Now, BE is straight ray

so ,

∠ACB + ∠ACE = 180°

60°+ ∠ACE = 180°

∠ACE = 180°-60°

∠ACE = 120°

Now, DC is straight ray  

so ,

∠ABC+∠ABD = 180°

70° + ∠ABD = 180°

∠ABD = 180° - 70°

∠ABD = 110 °
