Question

state whether the three angle can form a triangle or not . P = 100 degree ,Q = 80 degree and R = 50 degree

Answer 1

no, it can not form a triangle because the sum of all angle is bigger than 180°
as,
P+Q+R>180
100+80+50>180
230>180

hope this answer will help you.

Answer 2

no because sum of two angle is not greater than third angle
