Two angles of a traingle are 40degree and 60 degree calculate all its outer angles

Answer»

Answer:

140 120 and 100 degrees

Step-by-step explanation:

LET the triangle be ABC

Where Angle A B and C are 40 60 and x degrees RESPECTIVELY .

By Angle Sum Property

A +B +C=180

40+60+x=180

x=80

Outer angle of A is 180-40 =140

Outer angle of B is 180-60 =120

Outer angle of C is 180-80 =100
