Question

if one angle is 30 degree and other Angle is 60 degree . find the third angle of a triangle​

Answer 1

Answer:

90dgree by 30-60-90 degree angle theorem

Answer 2

Answer :

We use angle sum property, ie sum of the angles of a triangle is 180

Let the third angle be x

x + 30 + 60 = 180

x + 90 = 180

x = 180 - 90

x = 90°

Therefore the third angle is 90° and it is a right angled triangle...
