Question

∆a= 45°,∆B =65°,∆c =___​

Answer 1

Answer:

70°

Step-by-step explanation:

Let third angle = x

We know that, The sum of all angles of a triangle = 180°

So, therefore, 45° + 65° + x = 180°

45° + 65° = 110°

110° + x = 180°

x = 180° - 110° = 70°

so, x = 70°

Answer 2

Answer:

here is your ans

Step-by-step explanation:

we know sum of all angles of triangle equals to 180°

a + b + c = 180°

45° + 65° + c = 180°

110° + c = 180°

c = 180° - 110°

c = 70°

(therefore angle c = 70°)
