Question

two angles of the triangle are 40 degree and 70 degree find the third angle​

Answer 1

Answer:

70°

Step-by-step explanation:

According to the angle sum property of triangle the sum of all angles of a triangle is 180°.

So the third angle in this case will be

= 180° - ( 40° + 70°)

= 180° - 110°

= 70°

Have A Good Day!

Answer 2

Answer:

Let the third angle be x

we know that the sum of all angles of a triangle is 180°

So, 40°+70°+ x = 180°

110°+x = 180°

x = 180°-110°

x = 70°
