Question

ABC, AB AC and A-70°. Find and C​

Answer 1

Step-by-step explanation:

Since, AB = AC, therefore, ∠B=∠C

By angle sum property of triangle,

∠A+∠B+∠C=180

o

70

o

+2∠B=180

o

2∠B=110

o

∠B=55

o

Hence, ∠B=∠C=55

o

Answer 2

Solution :-

As, given AB = AC we get; ∠B = ∠C

• By angle sum property of triangle,

∠A +∠B +∠C = 180°

70° + 2∠B = 180°

           ∴  Hence, ∠B = ∠C = 55⁰

Final Answer :-

∠C = 55⁰
