Question

the sum of two angles of a triangle is 25 degree and 55 degree . find the third angle of the triangle​

Answer 1

Answer:

100 degrees

Step-by-step explanation:

Since, the sum of all the angles of a triangle is 180 degrees

The sum of third angle of triangle is

Let third angle be= x

ATQ

25+55+x = 180

80+x = 180

x= 180-80

x=100 degree

Answer 2

Step-by-step explanation:

By angle sum property of triangle ,

55 + 25 + x = 180

x = 180 - 80

x= 100
